Description

Hi, Trying to solve a large LP problem. The simplex works but CLP with the barrier method crashes. I'm using a w64 compiled version of the 1.16.11 CLP. I have tried with and without presolve, but it crashed in both cases.

I get this by debugging with VS Unhandled exception at 0x000000014015359B in clp.exe: 0xC0000005: Access violation writing location 0x00000000D8F00000. occurred

My model has 8760 hours. I made a version with only 5 hours and I was able to solve it with cbc barrier. So the issue seems to happen only with very large problems.
