[Bug c/35440] New: [4.1/4.2/4.3/4.4 regression] ICE resulting in completely broken diagnostic

[reichelt at gcc dot gnu dot org]

The following invalid code snippet triggers an ICE since GCC 4.1.0:

================================
struct A {};

void foo()
{
  (struct A){}();
}
================================

The compiler crashes trying to emit an error message, which results in a
completely broken diagnostic (e.g. file name and "internal compiler error"
message are missing):

'{
In function 'foo':
tree check: expected class 'expression', have 'exceptional' (constructor) in
pp_c_initializer_list, at c-pretty-print.c:1182
Please submit a full bug report, [etc.]

Before GCC 4.1.0 we got the error message:
bug.c: In function 'foo':
bug.c:5: error: called object '{}' is not a function
