I am using GLPK under octave interface for a mixed integer programming problem, however when running the solver I am facing the following error:

Assertion failed: a != a

The implication is that a is a NaN (not a number).
Somewhere a divison by 0, the square root of -1 or something
produced a NaN instead of aborting like a good debuggable program.
The NaN propagated until one of its children hit
the assertation designed just for such problems.

Error detected in file glpios02.c at line 134
panic: Aborted -- stopping myself...
