Thanks. I just tried this with the current gcc-2.95 prerelease sources and
it seems to be fine now.

egcs version: 1.1.2
system type: Alpha (linux)
command line: gcc -c -O2 bla.c
I get this:
egcs-bug.c: In function `main':
egcs-bug.c:42: internal error--unrecognizable insn:
(insn 162 154 69 (set (reg:SI 87)
(reg/v:DI 71)) -1 (insn_list 154 (nil))
(nil))
../../gcc/toplev.c:1385: Internal compiler error in function fatal_insn
This happens with -O2 and above. -O is ok.
This is the (heavily preprocessed and minimized) source that triggers it.
It was some huge source file but this example gives the exact same error:

This no longer fails with gcc 2.95, so apparently the bug
has been fixed.
