Unfortunately, a reproducer is the most I could find out with regard to this issue, which I noticed while working on #6548.
If a method with a declared return type (e.g.
mixed,object) is overridden with a class return type (e.g.stdClass), then there's a segfault somewhere in a very early stage, so not even an empty PHP script runs.Although the issue is reproduced via
ReflectionEnumUnitCase::getValue()which overridesReflectionClassConstant::getValue()- I only had to add amixedreturn type to the parent method -, but it is not limited to this case only. So I could trigger the same issue with other classes.
