rakudo-j does not crash, although it doesn't like it when the sub is called.

From @usev6

As a status update​: There is still a Null PMC access with Parrot. With Moar and JVM everything seems fine​:

$ perl6-p -e 'sub a is DEPRECATED((sub { "a" })()) { }; a();'
===SORRY!===
Null PMC access in get_bool()

$ perl6-j -e 'sub a is DEPRECATED((sub { "a" })()) { }; a();' ## identical output with perl6-m
Saw 1 call to deprecated code during execution.

Sub a (from GLOBAL) called at​:
  -e, line 1
Please use a instead.

Please contact the author to have these calls to deprecated code adapted,
so that this message will disappear!

@usev6 - Status changed from 'new' to 'open'

From @usev6

I added a test to S02-types/isDEPRECATED.t with commit Raku/roast@8022cc3d4c.

The test passes on MoarVM and JVM.

Since support for Parrot was suspended with Rakudo Star Release 2015.02, I'm closing this "parrot only" ticket.

I'll add the ticket to a list of closed ticket living in the mu repository​: https://github.com/perl6/mu/blob/master/misc/rt.perl.org/tickets_closed_parrot_only.txt.

In case support for Parrot will be restored in some future release the listed tickets can be checked and re-opened as appropriate.

@usev6 - Status changed from 'open' to 'rejected'
