[Bug bootstrap/32744] New: [4.3 regression] ICE in build2_stat, at tree.c:3077 bootstrapping on Tru64 UNIX

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

On both alpha-dec-osf4.0f and alpha-dec-osf5.1b, current mainline (as of
r126588) fails to bootstrap: 
/vol/gccsrc/obj/gcc-4.3.0-20070712/4.0f-gcc/./gcc/xgcc
-B/vol/gccsrc/obj/gcc-4.3.0-20070712/4.0f-gcc/./gcc/

/vol/gcc/src/gcc-dist/libgcc/../gcc/libgcov.c:838: internal compiler error: in
build2_stat, at tree.c:3077

This happens at -O and -O0 as well.

I've last bootstrapped successfully on 20070612.

Environment:
System: OSF1 hindemith V4.0 1229 alpha
Machine: alpha

host: alpha-dec-osf4.0f
build: alpha-dec-osf4.0f
target: alpha-dec-osf4.0f
configured with: /vol/gcc/src/gcc-dist/configure --prefix=/vol/gcc
--with-local-prefix=/vol/gcc --disable-nls --host alpha-dec-osf4.0f --build
alpha-dec-osf4.0f --target alpha-dec-osf4.0f --with-gmp=/vol/gcc
--with-mpfr=/vol/gcc --enable-languages=c,c++,fortran,java,objc,ada
--disable-libmudflap

How-To-Repeat:
Bootstrap mainline as described above.
