Could you please advise how to solve this problem?

Many thanks,

Junhua, the size of 642 rows and 772 columns domain seems pretty big. Have you tried to increase the RAM memory usage for Met4moves run? How much memory has been allocated for this run?

Thank you very much BH for the quick response! We tried 64G memory, but still has the same problem.

This (routine SETENVVAR() at line 804 in envgets.c) is a really-curious place for a seg-fault to be happening: that line is a Fortran-string copy that uses the Fortran trimmed string-lengths (and so should not be able to go out-of-bounds when fed proper Fortran CHARACTER strings). Is it possible that some of your strings have embedded ASCII-zeros or something like that, and are messing up the trimmed-length calculation?

Thank you very much Carlie! There is a blank line at the end of our file list. The problem was solved after we removed that line!
