[Bug c/35738] New: ICE with #pragma omp atomic and conversion from pointer to int

[reichelt at gcc dot gnu dot org]

The following valid code snippet triggers an ICE since GCC 4.2.0
when compiled with "-fopenmp":

=========================================
int foo();

void bar()
{
  int i;
  #pragma omp atomic
    i += foo;
}
=========================================

bug.c: In function 'bar':
bug.c:7: internal compiler error: in default_conversion, at c-typeck.c:1759
Please submit a full bug report, [etc.]

Without "-fopenmp" I only get a warning:
bug.c: In function 'bar':
bug.c:7: warning: assignment makes integer from pointer without a cast

The C++ frontend is not affected (you have to add "-fpermissive" to make it
compile).
