[Bug c++/36128] New: [4.4 regression] ICE with invalid argument for builtin

[reichelt at gcc dot gnu dot org]

The following invalid code snippet triggers an ICE on mainline:

====================================
void foo()
{
  __builtin_isless (foo, 0);
}
====================================

bug.cc: In function 'void foo()':
bug.cc:3: internal compiler error: Segmentation fault
Please submit a full bug report, [etc.]

The regression was introduced between 2008-04-19 and 2008-04-25.
Looking at the ChangeLog, the problem is likely fallout from

2008-04-24  Richard Guenther  <rguenther@suse.de>

        * typeck.c (cp_build_function_call): Call
        check_builtin_function_arguments.
