Joern,
Has anyone reported any problems to you about this patch? I am running into
a problem running the perl benchmark from SPEC2006 and I have tracked it down
to this June 16 patch (SVN 200133,
GIT ddba76b84c757d93b4247713d558724776149b62). I am building a GCC cross
compiler running on x86 linux and targeting mips-mti-linux-gnu.
I haven't been able to cut down perl into a smaller test case yet but starting
with this version of GCC, if I build perl with -O2 or -O3 and then run it with
this perl input:
% cat x.pl
#!./perl
{
eval {
use Math::BigInt;
$y = pack('w*', Math::BigInt::->new(5000000000));
};
}
1;
I get:
% ./perlbench_base.sellcey_reload x.pl
*** Error in `./perlbench_base.sellcey_reload': malloc(): memory corruption
(fast): 0x00642390 ***
and perl seems to go into an infinite loop. Before your change perl
ran and exited cleanly. I will try to create a smaller example but I wanted
to see if you (or someone else on gcc-patches) was seeing anything like
this on any other targets.
