Bootstrapping current mainline on Solaris 10/SPARC fails with an ICE in
stage2 (both with GCC 3.3.2 und 3.4.3 as bootstrap compiler):
stage1/xgcc -Bstage1/ -B/vol/gcc/share/sparc-sun-solaris2.10/bin/ -c -g -O2 -DIN_GCC

/vol/gnu/src/gcc/gcc-dist/gcc/java/check-init.c:899: internal compiler error: in

The problem vanishes with -O1, and I've been able to finish the bootstrap
by manually building java/check-init.o in stage2 and stage3 this way.
The error doesn't exist on Solaris 8/SPARC for some reason.
Environment:
System: SunOS padouk 5.10 s10_55 sun4u sparc SUNW,Sun-Fire-880
Architecture: sun4
host: sparc-sun-solaris2.10
build: sparc-sun-solaris2.10
target: sparc-sun-solaris2.10
configured with: /vol/gnu/src/gcc/gcc-dist/configure --prefix=/vol/gcc
--with-local-prefix=/vol/gcc --disable-nls --disable-libmudflap
How-To-Repeat:
Bootstrap mainline as above.
