Seg fault in Arc

[manuels]

I get a segmentation fault in https://github.com/mozilla/rust/blob/a88654977234d18b57e2a1842549941397ab0d59/src/libstd/sync/arc.rs#L83 in my program. (Find the full (complex and not really productive) program here)

I'm pretty new to rust.
How can I try to debug this segmentation fault?

Your program appears to have been removed, could you add it back up again?

A common reason for this is moving out of a capture variable multiple times in a loop, the compiler sadly doesn't currently prevent that. (#12041)

Second try: https://gist.github.com/manuels/9178144
Probably the issue you mentioned is present here.

[alexcrichton]

Aha indeed, https://gist.github.com/manuels/9178144#file-gistfile1-txt-L41 is a location where you're moving out in a loop (and there may be more).

Closing as a dupe of #12041

ok, thanks @alexcrichton! and sorry for the messy code. I was playing around with rust...
