Summary: Inverting and casting bit argument to char causes SIGSEGV

Initial Comment:
Inverting and casting a bit argument to a char causes SDCC to segfault.

Note that casting to unsigned char (or signed int) works fine.

void f(void)
{
	extern void g(char);
	extern __bit b;

	g(!b);			/* Causes SDCC 2.9.0 to segfault.. */
}

$ sdcc  -mmcs51  --model-small -c -o bit_bug.rel bit_bug.c
Caught signal 11: SIGSEGV

SDCC : mcs51 2.9.0 #5416 (May  7 2009) (UNIX)
