<section><title>Fixed Bugs and Malfunctions</title>
<list>
<item>
<p>
Several bugs concerning constant binary constructions
such as &lt;&lt;0:4294967295&gt;&gt; have been corrected.
Depending on the actual size of the binary and the type
of run-time system (32-bit, halfword, 64-bit), such
expression could either crash the run-time system or make
the loader refuse loading of the module.</p>

The Erlsrv utility failed to stop the erlang machine if
no StopAction was defined when the service was stopped.
This is now corrected.</p>

<p>
Due to a bug in glibc the runtime system could abort
while trying to destroy a mutex. A fix for this was
introduced in R14B02. This fix did, however, not solve
the problem. The runtime system will now issue a warning
instead of aborting.</p>

Replace atom in DRV macro in prim_file with string</p>
<p>
An experimental version of Dialyzer discovered that the
atom that replaced the DRV macro in prim_file ends up in
calls to erlang:open_port({spawn, Driver}, Portopts) as
the Driver argument. The documentation states that this
call requires a string there.</p>
<p>
This change is also consistent with the one introduced in
commit 0f03b1e9d2bef3bc830c31a369261af4c5234727 by Kostis
Sagonas.</p>

Fix bug related to hibernate and HiPE (clear
F_HIBERNATE_SCHED flag)</p>
<p>
F_HIBERNATE_SCHED flag that was introduced in
b7ecdcd1ae9e11b8f75e must be cleared in hipe_mode_switch
as well. Otherwise, processes running HiPE code that
hibernate, wake up and then trap into a BIF will not be
rescheduled.(Thanks to Paul Guyot)</p>

<p>
inet: error if fd does not match socket domain</p>
<p>
If an IPv4 fd is opened as an IPv6 socket, unexpected
behaviour can occur. For example, if an IPv4 UDP socket
is opened and passed into Erlang as an IPv6 socket, the
first 3 bytes (corresponding to 1 byte representing the
protocol family, 2 bytes set to the port) are stripped
from the payload. The cause of the UDP payload truncation
happens in inet_drv.c:packet_inet_input when a call to
inet_get_address fails silently because the family is set
to PF_INET6 but the buffer len is the size of an IPv4
struct sockaddr_in.</p>
<p>
(Thanks to Andrew Tunnell-Jones for finding the bug and
the test case!)</p>

erts: use a union to avoid strict aliasing issues</p>
<p>
Use a union for pointer type conversion to avoid compiler
warnings about strict-aliasing violations with gcc-4.1.
gcc >= 4.2 does not emit the warning. erts: adapt
matrix_nif to R14 erl_nif API changes (Thanks To Tuncer
Ayaz)</p>

<p>
Let epmd ignore empty ERL_EPMD_ADDRESS</p>
<p>
If the environment variable ERL_EPMD_ADDRESS is set to
the empty string, empd now behaves like it does by
default when ERL_EPMD_ADDRESS is unset. That is, in this
case, epmd now listens on all available interfaces
instead of using only the loopback interface, which
happened because epmd added the loopback address to the
(in this case empty) list of addresses specified via
ERL_EPMD_ADDRESS.</p>
<p>
Also, epmd now ignores ERL_EPMD_ADDRESS if it contains
only separator characters (comma and space).</p>
<p>
The same applies to epmd's -address option.(Thanks to
Holger Weiß)</p>

Add erlang:external_size/2 BIF</p>
<p>
This BIF's second parameter is a list of options.
Currently the only allowed option is {minor_version,
Version} where version is either 0 (default) or 1.

Fix enif_compare on 64bits machines</p>
<p>
In 64bits machines the Sint type has a size of 8 bytes,
while on 32bits machines it has a 4 bytes size.
enif_compare was ignoring this and therefore returning
incorrect values when the result of the CMP function
(which returns a Sint value) doesn't fit in 4 bytes.
(Thanks to Filipe David Manana)</p>

file is written. Also make sure that error/warning
reporting is consistent. (Thanks to Tuncer Ayaz)</p>

<p>
Two bugs in gen_sctp has been corrected: getopts/setopts
hence also send could only be called from socket owner,
and options 'linger', 'rcvbuf' and 'sndbuf' was read from
wrong protocol layer hence read wrong values by getopts.</p>

<p>When auxiliary work was enqueued on a scheduler, the
wakeup of the scheduler in order to handle this work
could be lost. Wakeups in order to handle ordinary work
were not effected by this bug. The bug only effected
runtime systems with SMP support as follows:</p> <list>
<item>Deallocation of some ETS data structures could be
delayed.</item> <item>On Linux systems not using the NPTL
thread library (typically ancient systems with kernel
versions prior to 2.6) and Windows systems, the <c>{Port,
{exit_status, Status}}</c> message from a terminating
port program could be delayed. That is, it only effected
port programs which had been started by passing
<c>exit_status</c> as an option to
<c>open_port/2</c>.</item> </list>
