Happens once in a while - still trying to build a repro case.

[niqdev]

Hi, I'm not actively developing this lib, feel free to open a pr to fix the issue and I'll be more than happy to review it and merge it.
Thanks

Does #83 solve this issue?

[ened]

@niqdev no, #83 covers performance only. This one is a hard crash.
