We get

(gdb) call debug_tree (*expr_p)
<nop_expr 0x7ffff5b99150
type <boolean_type 0x7ffff7ee4888 _Bool public unsigned QI
size <integer_cst 0x7ffff7ed2730 constant 8>

The FEs shouldn't feed us random crap really ...

Reduced testcase:
int main(void)
{
int gpf;
if(gpf ? (void) (0) : f ()) ;
}
--- CUT ---
Looking into it.

‘exceptional’ (error_mark) in get_narrower, at tree.c:7654
Now.
