[Bug ada/13670] New: xnmake gets miscompiled during bootstrap with ada enabled

["aj at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

If I bootstrap GCC 3.4 CVS with GCC 3.4 CVS as bootstrap compiler (including ada), 
it fails in:
(cd ada/bldtools; gnatmake -q xnmake ; ./xnmake -b ../nmake.adb )
make[2]: *** [ada/nmake.adb] Error 139
make[2]: Leaving directory
`/usr/src/packages/BUILD/gcc-3.4.0-20040113/obj-x86_64-suse-linux/gcc'
make[1]: *** [stage1_build] Error 2

Trying to debug this, I get:
/gdb ./xnmake

Note if I use GCC 3.3 as bootstrap compiler, this seems to work
