Description
Module: core feature 'class'
Description
Referencing a required:param class member in DESTROY, which had not been correctly initialised during instantiation, triggered a Segmentation fault.
FAO@leonerd,@ilmari - following up on IRC conversation. Many thanks!
Steps to Reproduce
This script is the most whittled-down example I could produce which exhibits the behaviour:
#!/usr/bin/env perluse v5.40;use experimentalqw/ class/;class Foo { field$dependency :param :reader;DESTROY {shift->dependency->cleanup; }}# Ooops, forgot to supply the dependencyFoo->new;
Expected behavior
Additional error:
Can't call method "cleanup" on an undefined value
