Consider this simple program:
use omp_lib
print *, 'Number of processors:', omp_get_num_procs()
end
After compiling this with "-fopenmp -static -fbacktrace", executing it gives
the output:
Number of processors: 2
Program received signal 11 (SIGSEGV): Segmentation fault.
Backtrace for this error:
+ function __restore_rt (0x41EAB0)
from file sigaction.c
The segfault is gone when compiling without the -static flag. Also this seems
to be a Fortran-only problem. An equivalent C program does not run into the
segfault.
