So it fails:
trying to find if an element exists in an AA
in a regex
invoked as a callback from curl
inside a parallel foreach.

Interesting that it just straight up core dumps, usually you'll 
get an exception.
see 
https://forum.dlang.org/thread/rrpmgzqqtkqgeicjdgps@forum.dlang.org for a recent discussion. What it the stack limit? 35 frames is a fair bit, could be a stack overflow. What is the return code? this will probably give you some info as to what happened.

Only other thing I can suggest is try linking against a debug 
phobos to see if you can get some more diagnostics.
