At first I thought that calling omp_max_thread() earlier in my program 
had solved the problem. Unfortunately, the error still occurs if I 
compile with OpenMP support but at the same time set the number of 
threads to 1 (i.e., no actual multithreading occurs). If I call 
omp_max_thread(2), although I use only a single thread, the error does 
not occur.
