Hello,

Edit: filed an issue at NREL/EnergyPlus#10245

I can reproduce the issue with energyplus 23.1.0

Starting Simulation at 06/15/2019 for RUN PERIOD 1
Segmentation fault: 11

I've transitionned your file to the (upcoming) V23.2.0 release, and ran it in debug. I do get some errors in the eplusout.err that are worth checking out

** Warning ** CalculateZoneVolume: 1 zone is not fully enclosed. For more details use:  Output:Diagnostics,DisplayExtrawarnings;
** Warning ** CheckUsedConstructions: There are 1 nominally unused constructions in input.
**   ~~~   ** For explicit details on each unused construction, use Output:Diagnostics,DisplayExtraWarnings;
** Warning ** DXFOut: Could not triangulate surface="CIRCTOIT1", type="Roof", check surface vertex order(entry)
**   ~~~   ** ...use Output:Diagnostics,DisplayExtraWarnings; to show more details on individual surfaces.
** Warning ** DXFOut: Could not triangulate surface="CIRCSOL2", type="Floor", check surface vertex order(entry)

I've enabled OutputDiagnostics, see full log below. I recommend you start by trying to fix these geometry errors.

Anyways, it still throws with a vectorissue. I've caught the crash, it happens here: https://github.com/NREL/EnergyPlus/bl...

BlNum is 0, which it shouldn't (the array is 1-indexed)
