host: mips-sgi-irix6.2

target: mips-sgi-irix6.2
configured with: ../srcdir/configure --enable-languages=c,c++,ada --prefix=/usr/local2 --disable-nls --disable-multilib
>Description:
The bootstrap process fails during stage 3 when the
stage 2 xgcc is used to compile the root file of the
Ada Standard library, the package Ada itself:

stage2/xgcc -Bstage2/ -B/usr/local2/mips-sgi-irix6.2/bin/ -c -g -O2      -gnatpg -gnata -I- -I. -Iada -I../../srcdir/gcc/ada ../../srcdir/gcc/ada/ada.ads -o ada/ada.o
xgcc: Internal error: Segmentation fault (program gnat1)
Please submit a full bug report.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

>How-To-Repeat:
Rerun the bootstrap.
>Fix:
Fix unknown, but behaviour observed in 3.4.0 and 3.4.1, too.
