MATLAB casadiMEX Crashing Issue

[Omkar Mulekar]

Hello,

I am using the OpenOCL package (found at https://openocl.github.io/), which uses CasADi for automatic differentiation.  I am running into an issue where MATLAB crashes completely when the script gets to a casadiMEX function (located at /Lib/casadi/casadiMEX.mexa64).  The weird thing is my scripts have worked on a dozen different devices, but I just recently started running it on an HPC, and that's where it started crashing.  When MATLAB crashes, it saves a dozen or so crash reports to my home directory.  One example is below.  I would greatly appreciate any help resolving this.  I also reached out to Mathworks, but they pointed me to reach out on here.

Sincerely,
Omkar Mulekar

Dear Omkar,

Can you make your problem reproduce with a small example?

The error sounds like mismatching openmp versions could be causing havoc,

but our binaries don't ship with openmp enabled, so that leaves me confused..

Best regards,
