Summary: internal compiler error: in emit_move_insn, at expr.c:2809

Initial Comment:

Writing some inline assembler, I missed an & on a struct, and gcc fails to put the whole struct in a register...

$ cat bug.c
struct { void *x[80]; } foo;
void bar( void ) {
    __asm__ ( "movl %%eax, %%ebx\n\t" : : "b" (foo) : "eax" );
}
$ i586-mingw32msvc-cc -c bug.c
bug.c: In function `bar':
bug.c:3: internal compiler error: in emit_move_insn, at expr.c:2809
