Script phpstan analyse handling the static-analysis event returned with error code 1

Q	A
Version(s)	5.2.0

Summary

Running PHPStan check with 128M of memory will run out of memory.
We should increase memory_limit to 256M - best place for this is probably in the composer command.

Current behavior

With the default memory_limit=128M on our WSL containers, PHPStan runs out of memory.

How to reproduce

Run the command composer static-analysis

Expected behavior

PHPStan needs to finish the analysis without running out of memory.
