This suggests that it is a library problem (it could be libf2c.a  
that is at fault, or an underlying library - such as the libc  
library on your OS).  Therefore, the following questions are  
relevant:

    * The libc version on your system (find out by "echo /lib/libc.so.*")

    * The binutils version on your system (find out with "as -v" or  
"ld -v")

    * The version of ldd/ld.so on your system (find out with "ldd -v")

(Copied straight from the pre-release questionnaire ...)

A complete Fortran program showing the problem would be nice too.

Thanks,
Toon.
