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).
