Segmentation Fault on OpenSM during IB Ping When using Ibsim

[ax75]

I setup ibsim using mofed drivers, started the ibsim with net-example sample topology. When trying to perform ibping with any LID number the opensm crashes with segmentation error.

OpenSM & Ibsim Version
OpenSM 5.17.2.MLNX20240610.dc7c2998

ibsim 0.12
