Confirmed. Here's a reduced testcase that crashes when compiled under
i686-pc-linux-gnu:
=========================================
typedef double* va_list;
void __builtin_va_start(va_list, ...);
void foo(const char* s, ...)
{
va_list v;
__builtin_va_start(v, s);
}
=========================================
bug.c: In function 'foo':
bug.c:8: internal compiler error: in convert_move, at expr.c:371
Please submit a full bug report, [etc.]
I don't know whether messing around with va_list and __builtin_va_start
is allowed or not. Btw, with
typedef void* va_list;
instead of
typedef double* va_list;
I get a different ICE:
bug.c: In function 'foo':
bug.c:8: internal compiler error: in simplify_subreg, at simplify-rtx.c:4918
Please submit a full bug report, [etc.]
Btw, the ICE appeared in GCC 4.0.0 (GCC 3.3.x crashed, too).
