forrtl: severe (174): SIGSEGV, segmentation fault occurred

Dear all,

I got stuck with the following error,

forrtl: severe (174): SIGSEGV, segmentation fault occurred

I tried to follow the instruction here to solve it,

https://software.intel.com/en-us/articles/determining-root-cause-of-sigs...

$ ifort -heap-arrays 256000000

$ ulimit -s unlimited

but none of the above methods worked.

Does anyone know how to deal with this?

Best regards,
