Process terminated with status -1073741819 on Windows

According to https://docs.microsoft.com/en-us/openspecs/windows_protocols/ms-erref/596a1078-e883-4972-9bbc-49e60bebca55 this is a memory access violation. I've only seen this happening in one specific case, on Windows. When I run the same conversion on macOS it works fine.

As is usually the case with memory errors I have no clue where to begin looking for the bug. The bug could be in Liblouis but I think chances are higher that it is a Liblouisutdml bug.

Does anyone have a list of unsolved memory related bugs that have been identified in Liblouisutdml? Do the sanitizer checks that have been added recently help?
