I am fairly sure this started about May 5th, but unfortunately the commits about this time make denemo un-compilable, so it is difficult to test. My suspicion is that it is this change:
commit b56cad8dba8df69afcdf5d32afd1c665d011d3b9 added an external program to generate commands.c I think it causes a memory corruption which then shows itself in unpredictable ways.
