DBIish tests started to fail (with segv) after this rakudo commit:
rakudo/rakudo@ff063e7
The bump itself brought these MoarVM changes:
MoarVM/MoarVM@2017.09.1-602-g676723d...2017.09.1-608-ge051ee3
Committable output before and after:
command: commit: ff063e7b53^,ff063e7b53 https://gist.githubusercontent.com/AlexDaniel/13a57dbb993d624c877befc137c33ee6/raw/a575bf2e04e24ced60b35665a4ec5a3324369c47/dbiish.p6
output: https://gist.github.com/e25c6a14d6078e99f6bb46de494565b1
Not surprisingly there's no crash with MVM_JIT_DISABLE:

Offending commit reverted in MoarVM/MoarVM@1a9be0a
I tested it with moar HEAD and indeed the issue is no longer there. So it should work fine after moar and nqp bumps.
｢testneeded｣ ?

Honestly, I have no idea how to test this… maybe someone should attempt to golf it, but given that the commit description is “JIT compile native calls”, I guess it'd be a bit complicated.
… I'm fine with just delegating it to the DBIish test suite…
