Sorry, my bad. The shared variable is on the stack, so I had to add a taskwait at the end (code follows). A warning would have been nice...
--- start c code ---
void recurse(int levelsToGo)
{
if ( levelsToGo == 0 )
{
printf("*");
}
else
{
#pragma omp task shared(levelsToGo)
{
recurse(levelsToGo-1);
}
#pragma omp task shared(levelsToGo)
{
recurse(levelsToGo-1);
}
#pragma omp taskwait
}
}
--- end c code ---
