I know this is invalid, but:
- it produces a warning, not an error;
- reliable compilers never crash, do they?
Testcase:
--------------------------
void f(void)
{
register int x asm("eax");
g(&x);
}
--------------------------
objdir/gcc/xgcc -Bobjdir/gcc -c f.c
f.c: In function âfâ:
f.c:5: warning: address of register variable âxâ requested
f.c:5: warning: address of register variable âxâ requested
f.c:5: internal compiler error: in expand_expr_addr_expr_1, at expr.c:5975
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

Sorry, an empty line disappeared when I cut&pasted the code. f.c:5 is actually
the line "g(&x);".
