I get the following error when compiling using gcc snapshot 4.4.0 20080704
main.c|18|internal compiler error: in pop_gimplify_context, at gimplify.c:194
See code at the end of the post and gcc configure options.
Obviously when removing the -fopenmp switch the ICE go away. Also removing
either the omp task or omp single directive make the error go away. The ICE
also vanish if the expression inside the while loop is a constant.
This error appear at all optimization level with or without debugging enabled.
using the following code (reduced case...) :
int main()
{
int i = 0;
#pragma omp parallel
{
#pragma omp single
while( i < 1 )
{
#pragma omp task
i++;
}
}
return 0;
}
gcc configure options :
$ gcc -v
Using built-in specs.
