Greetings Porters,

While attempting to build a quadmath Perl on my shiny new 64-bit Debian VM, using the following command​:

./Configure -Dusedevel -Dcc='ccache gcc' -Duselongdouble -Duse64bitall -Dusequadmath -Uman1dir -Uman3dir -des

During `make`, I had the following error when make tries to test the built miniperl​:

./miniperl -w -Ilib -Idist/Exporter/lib -MExporter -e '<?>' || sh -c 'echo >&2 Failed to build miniperl. Please run make minitest; exit 1'
Perl v1305670057.0.0 required--this is only v5.23.4, stopped at dist/Exporter/lib/Exporter.pm line 3.
Compilation failed in require.
BEGIN failed--compilation aborted.
Failed to build miniperl. Please run make minitest

`make minitest` has the same errors. A build with the same ./Configure but -Uusequadmath successfully builds and tests with no failures, except for an unrelated failure in Porting/libperl.t. The build log is attached, the only remarkable warning is several instances of​:

warning​: implicit declaration of function ‘quadmath_snprintf’ [-Wimplicit-function-declaration]

The decimal number `v1305670057` does not seem to be remarkable, 0x4DD2F1A9. Valgrind reports no errors.

Updating makefile...
Now you must run 'make'.

If you compile perl5 on a different machine or from a different object
directory, copy the Policy.sh file from this object directory to the
new one before you run Configure -- this will help you with most of
the policy defaults.

Greetings Porters,

While attempting to build a quadmath Perl on my shiny new 64-bit
Debian VM, using the following command​:

./Configure -Dusedevel -Dcc='ccache gcc' -Duselongdouble -Duse64bitall
-Dusequadmath -Uman1dir -Uman3dir -des

During `make`, I had the following error when make tries to test the
built miniperl​:

./miniperl -w -Ilib -Idist/Exporter/lib -MExporter -e '<?>' || sh -c
'echo >&2 Failed to build miniperl. Please run make minitest; exit 1'
Perl v1305670057.0.0 required--this is only v5.23.4, stopped at
dist/Exporter/lib/Exporter.pm line 3.
Compilation failed in require.
BEGIN failed--compilation aborted.
Failed to build miniperl. Please run make minitest

`make minitest` has the same errors. A build with the same ./Configure
but -Uusequadmath successfully builds and tests with no failures,
except for an unrelated failure in Porting/libperl.t. The build log is
attached, the only remarkable warning is several instances of​:

warning​: implicit declaration of function ‘quadmath_snprintf’ [-
Wimplicit-function-declaration]

The decimal number `v1305670057` does not seem to be remarkable,
0x4DD2F1A9. Valgrind reports no errors.

Playing with this calculator, http​://babbage.cs.qc.edu/courses/cs341/IEEE-754.html

FP 5.006 as float 32 is 0x40A03126, as float 64 is 0x4014062,4DD2F1AA0 (comma inserted by me). Notice your "0x4DD2F1A9" is very close to low 4 bytes of the float 64 which are "0x4DD2F1AA0". I've seen stuff like this before when the %f is used instead of %lf in Perl_my_snprintf, and is it really 8 bytes or 10/12/16 byte floats.

That surprises me because at least in standard C printf there is no way
to pass floats to it (it's a vararg function).

printf %f takes a double, not float.

printf %lf had undefined behavior in C89/C90 but was made equivalent to
%f in C99.

C99 added long double, with printf format %Lf.

...

Now I'm looking at the code in util.c.

There's a potential memory leak in Perl_my_snprintf/USE_QUADMATH.
quadmath_format_single can return a malloc'd string. If
quadmath_snprintf returns -1, perl croaks without freeing qfmt.

This also applies to sv.c. And what's up with this error message?

Perl_croak_nocontext("panic​: quadmath_snprintf failed, format \"%s|'",
qfmt);

|' looks like someone messed up their shift key while typing \".

Build with -Duselongdouble or -Dusequadmath - not both.

Building with both confuses the build, mostly because parts of the process test quadmath first and others test longdouble first.

The attached makes Configure abort if both are provided.

I considered having one override the other - but which did the user really want?

I accidentally triggered this again today while debugging something else.
Any chance Tony's patch can be applied?
