I've tried to reproduce this today (both on a normal build, plus a build with GC stressing to shake out corruption bugs), but am unable to on Rakudo and MoarVM HEAD revisions. We've done a number of fixes for things that resulted in SEGV in recent days, so it's possible that one of those covered it. Any chance you could try on latest and see if this still happens? Thank you, Jonathan

for me, with this version it still segfaults:
MacBook-Pro-de-Fernando:Test-Fuzz fernando$ perl6 -v
This is Rakudo version 2016.12-49-gb8df3a6 built on MoarVM version 2016.12-18-ga645d7e
implementing Perl 6.c.

HI there!

I was trying to reduce the code, but I couldn’t…
Some times I get a segfault running this code:

perl6 -Ilib -MTest::Fuzz -e 'sub bla(Int $a) is fuzzed {42}; run-
tests’

on branch “role” of https://github.com/FCO/Test-Fuzz/tree/role
<https://github.com/FCO/Test-Fuzz/tree/role>

I'm sorry the big code…
