....I don't know whether it will help, but you might try reducing the level
of optimization for this file.
You could also try downloading, compiling and installing the latest
gcc/g77 version (e.g. from )
Since it seems to be worth the effort, you could also get the Intel
c/c++/fortran compilers for linux, which are free and usually produce
faster code. Version 7.1 can be obtained from
and Version 8.0 is also due to be released soon.
Unfortunately, the intel compilers are more error prone than gcc
(version 8.0 too),but they should work in this case.
Hope it helps
