Version|4.8.1 |4.7.2
--- Comment #3 from Jonathan Wakely <redi at gcc dot gnu.org> ---
I can reproduce this with Fedora 20's system compiler:
gcc version 4.8.2 20131212 (Red Hat 4.8.2-7) (GCC)
Only when configured with --disable-bootstrap:
../gcc-4.7.2/configure --disable-bootstrap --enable-languages=c,c++

../../../../gcc-4.7.2/libgcc/libgcc2.c: In function ‘__absvdi2’:
../../../../gcc-4.7.2/libgcc/libgcc2.c:273:1: internal compiler error:
Segmentation fault
However it doesn't happen with 4.7.3 using the same configuration and same host
compiler.
