I think the QP code does not check that HiGHS hit the time limit in computeStartingPointHighs. Also, I think the code may try to set a negative time limit for HiGHS. I have tried to fix this (https://github.com/fwesselm/HiGHS/tree/QpTimeLimit), but I do not know the QP code well.
Originally reported as jump-dev/HiGHS.jl#240
MPS file: time_crash.mps.txt
Very reproducible in HiGHS v1.7.2 and v1.8.0, on both Windows and Mac, and every time.
