Large memory consumtion

[fezfez]

Bug report

When a run phpstan i got a large memory consumption (2G~) on code base with 2500 class
After running phpstan with --debug -vvv option i found a class that consume 338MB (!).

Code snippet that reproduces the problem

i made a little repository with a complete reproduction case https://github.com/fezfez/phpstan-memory

Expected output

I think the expected output must be the same usage of memory, because none of the class are used.

[mergeable]

This bug report is missing a link to reproduction on phpstan.org.

It will most likely be closed after manual review.
