Default Bug#670164: ICE: Segmentation fault when compiling MPFR's set_f.c

Package: gcc-snapshot
Version: 20120407-1
Severity: important

When building MPFR (flags branch, r8151), using:

$ ./config.status -V
MPFR config.status 3.2.0-dev
configured by ./configure, generated by GNU Autoconf 2.68,
with options "'--with-gmp=/usr/local/gmp-debug' '--enable-assert=full' '--enable-logging' 'CC=gcc-snapshot' 'CFLAGS=-Wall -O3 -march=native -std=gnu99'"

via a script, I got:

set_f.c: In function 'mpfr_set_f':
set_f.c:27:1: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <file:///usr/share/doc/gcc-snapshot/README.Bugs> for instructions.
Preprocessed source stored into /tmp/ccxGnHHi.out file, please attach this to your bugreport.

Attached.

I don't have the time to look at this more closely.
Perhaps in a few hours or tomorrow.

Default Bug#670164: ICE: Segmentation fault when compiling MPFR's set_f.c

tags 670164 upstream
forwarded 670164 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=52639
thanks

Here's a simple testcase:

// /usr/lib/gcc-snapshot/libexec/gcc/x86_64-linux-gnu/4.8.0/cc1 -fpreprocessed ice-setf.i -march=corei7 -mcx16 -msahf -mno-movbe -mno-aes -mno-pclmul -mpopcnt -mno-abm -mno-lwp -mno-fma -mno-fma4 -mno-xop -mno-bmi -mno-bmi2 -mno-tbm -mno-avx -mno-avx2 -msse4.2 -msse4.1 -mno-lzcnt --param l1-cache-size=32 --param l1-cache-line-size=64 --param l2-cache-size=8192 -mtune=corei7 -quiet -dumpbase ice-setf.i -auxbase ice-setf -O3 -std=gnu99 -o - -frandom-seed=0
# 1 "ice-setf.i"
int a(int *, unsigned long);
int g(unsigned long);
void r(int, long);

int foo(unsigned long sy, int *x, int i)
{
unsigned long sx = x[0];
if (sy <= sx)
{
unsigned long p = sx * 64;
int m = 0;
int tmp = i ? g(sx) : a(&m, sx);
r(tmp, p);
}
return 0;
}

$ gcc-snapshot -O3 -march=native -std=gnu99 -c ice-setf.i
ice-setf.i: In function 'foo':
ice-setf.i:5:5: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <file:///usr/share/doc/gcc-snapshot/README.Bugs> for instructions.

The ICE is reproducible with -O3, but not with -O2.

I'm trying to submit this upstream, but GCC's bugzilla is currently
down.

tags 670164 fixed-upstream patch
thanks

I've attached the patch from upstream (only the fix, not the testcase).
I've checked that it solves the problem.
