I am using GCC 4.4.0 20080829 (experimental).

$ cat u.c
void f(unsigned long x);

void g(long x)
{
    f((unsigned long)(-1-x)+1);
}
$ gcc -c u.c
u.c: In function 'g':
u.c:4: error: non-trivial conversion at assignment
D.2087
x
D.2087 = -x;

u.c:4: internal compiler error: verify_gimple failed
Please submit a full bug report,
with preprocessed source if appropriate.
