GC Seg fault

[raghur]

So I wrote a small module and then when I call it from python, it works fine if it's just a single call.

OTOH, if I call it in a loop - even say just 100 times, then after the 20th time there's a crash [on windows, the debug window opens, on linux I get a message about the GC]

I also tried building with --gc:none and in this case, the program completes successfully.

Are there guidelines/dos & donts in terms of what data can be returned from nim?

Happy to share code if you want to drop me an email at raghu dot nospam at gmail

Do you happen to use the non-devel version of nim that doesn't have this patch yet? nim-lang/Nim#7885

[raghur]

Yes - I'm on nim 0.18 - Nim Compiler Version 0.18.0 [Windows: amd64]

Should I try the devel version?

[yglukhov]

Yes please

[yglukhov]

I assume that nails it. If not, feel free to reopen.

[raghur]

Works with the dev build without issues. Thanks!
Probably a good idea to put that on the README?

Kinda duplicate of #11
