program hangs when SYSTEM() calls gzip



I have installed Intel Parallel Studio XE w019 Update 1 Composer Edition and am running an OpenMP-parallelised fortran code under Windows 10.

The program hangs indefinitely when executing SYSTEM() command which compresses the output files by gzip (the output is dumped every predefined number of steps) :

ber='gzip -f '//p_ou(1:len_trim(p_ou))//'*.dat'

e=SYSTEM (ber)

The program only resumes if a key is pressed but then it hangs again (not necessarily on the next output dump).

However, I am running the same code under Windows 8.1 pro and the program runs without problems.

Do you have any idea what could be causing the program to hang under Windows 10 and could you suggest a workaround?

The program runs twice faster under Windows 10, so I would like to find a solution to this problem.

Thank you in advance

Gaby S.
