Description Krzysztof Pawlik 2011-03-14 19:34:15 UTC 
User-Agent:       Mozilla/5.0 (X11; U; Linux x86_64; en-US) AppleWebKit/534.16 (KHTML, like Gecko) Chrome/10.0.648.133 Safari/534.16

(Side note: OS list is missing 11.4)

On fresh openSUSE 11.4 install I get ICE during compilation of Google gflags 1.5:

if /bin/sh ./libtool --tag=CXX --mode=compile g++ -DHAVE_CONFIG_H -I. -I. -I./src  -I./src  -pthread -DNDEBUG -O3 -march=k8 -pipe -MT libgflags_la-gflags.lo -MD -MP -MF ".deps/libgflags_la-gflags.Tpo" -c -o libgflags_la-gflags.lo `test -f 'src/gflags.cc' || echo './'`src/gflags.cc; \
then mv -f ".deps/libgflags_la-gflags.Tpo" ".deps/libgflags_la-gflags.Plo"; else rm -f ".deps/libgflags_la-gflags.Tpo"; exit 1; fi
libtool: compile:  g++ -DHAVE_CONFIG_H -I. -I. -I./src -I./src -pthread -DNDEBUG -O3 -march=k8 -pipe -MT libgflags_la-gflags.lo -MD -MP -MF .deps/libgflags_la-gflags.Tpo -c src/gflags.cc  -fPIC -DPIC -o .libs/libgflags_la-gflags.o
src/gflags.cc: In member function âbool google::<unnamed>::FlagValue::ParseFrom(const char*)â:
src/gflags.cc:1958:1: internal compiler error: Aborted

Reproducible: Always

Steps to Reproduce:
1. Download gflags 1.5
2. CXXFLAGS="-O3 -march=k8 -pipe" ./configure --enable-static --enable-shared
3. make

Alternatively: try to compile attached preprocessed source:
# g++ -O3 -march=k8 -pipe libgflags_la-gflags.i -c -o /dev/null
Actual Results:  
ICE.

Expected Results:  
Successful compilation.

# g++ --version
g++ (SUSE Linux) 4.5.1 20101208 [gcc-4_5-branch revision 167585]


Bug is present when using -On where n is >= 1, with -O0 it works - source is compiled correctly.

Comment 2 Richard Biener 2011-03-15 09:36:01 UTC 
I can't reproduce it.  GCC doesn't abort itself but instead it looks like it
might be gmp or mpfr that is aborting.  Can you capture a backtrace with gdb?
Append -v to the command-line and run the printed cc1plus command in gdb.
Comment 3 Krzysztof Pawlik 2011-03-15 16:04:05 UTC 
Indeed it's gmp issue, here's gdb session output:

Can this be related to the fact that this system is running as virtual machine under KVM?
Comment 4 Richard Biener 2011-03-15 16:31:33 UTC 
Yes.
