--gc:arc SIGSEGV, while --gc:refc works fine.

Code: https://gist.github.com/treeform/038fe8269f149678e199a71fb8c5388d

I was looking at some benchmarks from https://github.com/kostya/benchmarks#mandelb to try out with arc, this one does not work

Crash:
nim c --gc:arc -d:release /p/nimbench/bf.nim

While this works:
nim c --gc:refc -d:danger /p/nimbench/bf.nim

@treeform can you fix the title? s/arg/arc (to make it more searchable)

[timotheecour]

I realized the code you provided is large, can you try to generate a minimal example? this helps with de-duping (eg is this same as #13137 ?) and fixing

I just tested this on latest devel and it works for me with no SIGSEGV. Maybe it's fixed?

Reopen if still a problem, we fixed plenty of bugs.
