If you want to investigate this for similarities, , you could debug a release build of your issue, and look at the assembly line that the crash occurs on. Easy way to verify if it is an alignment issue, would be to confirm that the crash occurs on a movaps instruction like this one does, and then hotpatch that to movups instead, and see if the crash goes away…
Otherwise, want to post a minimal sample for repro on your question, and I’ll try to see what I can spot?
