[Bug target/27082] segfault with virtual class and visibility ("hidden")

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

------- Comment #4 from tbm at cyrius dot com  2006-05-16 21:11 -------
Hmm, that's interesting.  When I call g++ from a Makefile I get a
"unrecognizable insn" error but calling it directly leads to the segfault. 
I've no idea if this "unrecognizable insn" error is helpful in any way but I
thought I'd mention it here.

Anyway, I can confirm this segfault on Alpha with gcc 4.0/4.1/4.2.

g++ -c test.c
