A large array in source code locks up phpstan since version 0.12.95

Bug report

Happens in 0.12.95 and 0.12.96. It worked fine in 0.12.94.

phpstan seemingly just gets stuck on that file and does not quit.

Code snippet that reproduces the problem

Expected output

phpstan doesn't lock up

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

It will most likely be closed after manual review.

I was able to bring it down to a minute with this optimization: phpstan/phpstan-src@5a44c29

Is that sort really so slow? Seems odd.

I tried f7ede5f build, and it is still slow. There is definitely a regression that happened since 0.12.94.

[ondrejmirtes]

The "regression" is that huge union stays a union and is interpreted precisely.

With dev-master at least it finishes in a reasonable amount of time.

One way to solve this is not to analyse files like that - there's little value in that.
