Hello,

I am getting an error for some problem formulations, but I am unable to track 
down any cause.

The command prompt log reads:

Assertion failed: piv1 != 0.0
Error detected in file ..\src\glpspx02.c at line 2996


Is this information useful or is any additional information needed? The entire 
log is provided below. Thank you for your time, Matt
