| Subject: | Issue With DEMOLISH and lazy attributes |
I am running into issues where attributes are not defined during global object destruction:
(in cleanup) Can't call method "initialize" on an undefined value at
.../Class/MOP/Method/Meta.pm line 48 during global destruction.
This seems to only happen for objects with lazy attributes that are being accessed during the
DEMOLISH method. It does not happen in normal Moose objects. There are cases where no error
appears as well, but this may be non-determinism on the part of the GC when the DEMOLISH
method is running...
