From @lizmat

$ perl6 —ll-exception -e 'my @​a = (^10000)>>.Str' segfaults,

$ perl6 —ll-exception -e 'my @​a = (^1000)>>.Str’ doesn’t

testing with some values, it looks like any value beyond 9700 makes it almost always crash. Just below that it only crashes occasionally.

This is Rakudo version 2017.07-84-gc1e41f9 built on MoarVM version 2017.07-253-g82c282e

Closable with rakudo tests then.

Actually, I've been trying to reproduce it on the said revision with --profile, --ll-exception and whatnot, and I can't. I think this is an issue on OS X and therefore should be confirmed (and tested) on OS X also.
