Subject: [PATCH] Fix reference-counting in set_event_filter
|
||
|
|
|
||
|
|
This previously resulted in the following test failure with Perl 5.38.2
|
||
|
|
on Debian unstable (https://bugs.debian.org/1064761):
|
||
|
|
|
||
|
|
t/core_events.t ................. 1/? Can't use an undefined value as a subroutine reference during global destruction.
|
||
|
|
t/core_events.t ................. Dubious, test returned 22 (wstat 5632, 0x1600)
|
||
|
|
All 691 subtests passed
|
||
|
|
(less 1 skipped subtest: 690 okay)
