The following code:

void x(void);
void x(void)
{
  unsigned a, b;
  asm volatile ("" : "=rax" (a), "=rcx" (b) : "0" ((unsigned long) 0x0));
}

compiled with gcc-4.3 -m64 -O -c x.i 

emits:

x.i: In function ‘x’:
x.i:7: internal compiler error: in inline_secondary_memory_needed, at
config/i386/i386.c:21770
Please submit a full bug report,
with preprocessed source if appropriate.
See <file:///usr/share/doc/gcc-4.3/README.Bugs> for instructions.

Omitting -O compiles the file.

Making a and b unsigned longs also fixes it.

Using built-in specs.
