Seg fault on world generation

[i2amroy]

I'm getting this happening occasionally but I haven't been able to reproduce reliably yet.

[minakitty]

Could this be related to #3137 ?

I get a reproducible (read 100%) segfault on world generation on two systems up till b381798.

It doesn't seem related to #3137 but since the OP has no further info i'll hijack this issue.

I haven't touched cataclysm for a few weeks so i can't tell when this started but if the backtrace is of no use I'll bisect it when i have some time.

This doesn't happen as of 1af62d1.

[dwarfkoala]

Is this fixed? Can it be closed?

[namarrgon]

I didn't have time to bisect it but since my last comment it works-as-expected™.

Close it. It can always be reopened if the problem reemerges.
