Probably the result of mismatched C libraries.
gcc 3.0 uses a different standard library from previous versions.
It is almost compatible with previous versions.
Using ctype.h is a sure way to preclude mixing binaries.
The way to make it work is to ensure that you use the same
version of gcc that was used to compile GLPK.

This come up a lot elsewhere.  It belongs in a lot of FAQs.
