Avoid corrupt oversized integer to be created from binary
matching. Instead throw system_limit exception which is
the correct behavior. A peculiar symptom of this bug was
that bitwise operations (band, bor, bxor) on such
oversized integers could return the empty list [].

<section><title>Common_Test 1.10</title>

<section><title>Fixed Bugs and Malfunctions</title>

<p>
The tests overview file, index.html, did not always get
updated correctly after a new test run. This was because
of a bug in the Common Test log cache mechanism which has
now been corrected.</p>
<p>
Own Id: OTP-11400</p>
</item>
<item>
<p>
When a successful test case returns, Common Test should,
according to the documentation, send a tc_done event to
the event handlers with Result = ok in the data field.
However, Common Test sets Result to the return value of
the test case instead. Common Test has been modified now
to comply with the documentation.</p>

A ct_telnet:expect/3 call could never be aborted before
an idle_timeout, even if total_timeout had been set to a
lower value (i.e. a shorter time). This problem has been
fixed.</p>
<p>
Own Id: OTP-12335</p>
</item>
<item>
<p>
The undocumented return value {skipped,Reason} from
config functions and test cases was handled
inconsistently. Test cases were e.g. reported as
"skipped" to CT Hook functions, but "successful" to event
handlers. Now, the above return value is consistently
handled the same way as {skip,Reason} and this has also
been documented.</p>

<p>
The Erlang source code to HTML generator would sometimes
fail because epp:parse_erl_form/1 could not find and
expand required macros in included header files. The
problem has been solved by making sure common_test always
passes the full include path to epp. Also, a bug that
could cause erl_syntax:revert/1 to fail because of a
badly formed syntax tree has been corrected.</p>
<p>
Own Id: OTP-12419</p>

<p>
A missing group option in the ct_run help text has been
added.</p>

<p>
Printouts by means of ct:log/2/3 or ct:pal/2/3 from the
hook functions on_tc_fail/2 and on_tc_skip/2 would (quite
unexpectedly) end up in the "unexpected i/o" log file
instead of in the test case log file. This behaviour has
been changed so that now, all printouts (including stdio
printouts) from these hook functions will be routed to
the test case log file.</p>

<p>
ct_netconfc:action/3 will now - if the return type is
void - accept an RPC reply on the form
{ok,[simple_xml()]}, and in this event return only the
atom ok.</p>

OTP-11971 erroneously changed the handling of relative
paths for incl_dirs specified in the cover spec file.
This is now corrected so these are expected to be
relative to the directory where the cover spec file
itself is stored</p>
<p>
Own Id: OTP-12498 Aux Id: OTP-11971 </p>
</item>
<item>
<p>
Some test cases have been updated to use ct:sleep/1
instead of timer:sleep/1. The reason being that the sleep
times need to be scaled to compensate for slow execution
(e.g. when cover is running).</p>

Common Test now exports a function,
ct:get_event_mgr_ref/0, that returns the name of the
Common Test event manager. This makes it possible to plug
in event handlers to the event manager while tests are
running (using the gen_event API).</p>
<p>
Own Id: OTP-12506 Aux Id: seq12802 </p>
</item>

<p>
When a test case (or configuration function) fails
because of an exit signal from a linked process, Common
Test previously passed only the reason for process
termination to the CT post hook functions and the event
handlers (in the tc_done event). This has been changed so
that now the tuple {'EXIT',ReasonForProcessTermination}
is passed instead. This makes it much easier in the CT
post hook functions to distinguish a failure of this sort
from other types of errors and from the return value of a
successful test case.</p>

<p>
A new feature has been introduced in ct_telnet:get_data/1
that makes it possible to automatically poll the telnet
connection in case an incomplete string (one that has not
yet been terminated by a newline) remains in the receive
buffer. The polling is controlled by two new telnet
config values, which are documented in the ct_telnet
reference manual. The polling mechanism is disabled by
default (making the get_data/1 function backwards
compatible).</p>

<p>
Matching out a map from a record and then updating the
record could cause a 'badarg' exception at run-time.
(Thanks to Dmitry Aleksandrov for reporting this bug.)</p>

<p>The compiler would crash when compiling some complex,
nonsensical guards such as:</p>
<p> ... <c>when {{X}}, -X</c>...</p>
<p>
Own Id: OTP-12410</p>
</item>
<item>
<p>
In rare circumstances, using binary pattern in the value
part of a map pattern would cause the compiler to crash.</p>
<p>
Own Id: OTP-12414</p>
</item>
<item>
<p>Case expressions where a map was wrapped in a tuple or
list such as:</p>
<p><c>case {a,Map} of</c><br/> <c>{a,#{k:=_}}=Tuple -&gt;
Tuple</c><br/> <c>end.</c></p>
<p>would be unsafely "optimized" to either cause an
exception at run-time or would return an empty map.</p>
<p>
Own Id: OTP-12451</p>
</item>
<item>
<p>When a variable was compared to a literal map using
the '<c>==</c>' operator, the compiler would change the
operator to '<c>=:=</c>' since it is more efficient.
However, this optimization is not safe if the map literal
has numeric keys or values. The compiler will now only do
the optimization if all keys and values are
non-numeric.</p>
