XPRSmipoptimize - received signal SIGFPE, Arithmetic exception.
I am working on a program written in Pascal that's failing to optimize a MIP problem using XPRESS. The problem is created with XPRSloadmip and optimized with XPRSmipoptimize. In order to debug this ...
By default the console optimizer runs with floating point exceptions disabled, this is probably why you don't get an exception there.
Could you try to explicitly disable floating point exceptions in your Pascal program? You would have to do something equivalent to feenableexcept(), see for example here.
If this fixes the problem, you could try to figure out which of the exceptions is thrown (inexact, invalid, overflow, underflow, divbyzero) and then potentially only disable that exception.
So far I have only been able to produce an "inexact" exception here with your model and that exception is expected in certain places.
