(Psalm 5.7.4@c46eccda769925073b8f65d66c4a3a7dc5d440b1 crashed due to an uncaught Throwable)

I tried with 5.7.0 5.7.1 and now today with 5.7.4 same thing.

I am on apple silicon with php 8.2 (PHP 8.2.3 (cli) (built: Feb 15 2023 00:18:01) (NTS))

And the funny thing is, I added var_dump to the file/variables throwing this error:

Am I just missing something silly or shouldnt int(1) !== int(1) supposed to return false instead of true like it does here

I am trying to fiddle it out but if anyone has more experience and can point a finger to something that i am failing to see, that will be much appriciated.

Hey @gcg, can you reproduce the issue on https://psalm.dev ?

Hey @gcg, can you reproduce the issue on https://psalm.dev ?

hey bot, the error seems to be coming from psalm directly, not because of my code.

but i did check on a different codebase/project on the same machine just to be safe, updated psalm from 5.6 to 5.7.4 and got the same error.

[gcg]

As an update, can't replicate this on the same php version with a x86 linux.

Yes, this is a known PHP bug, it was fixed by php/php-src@70ff10a and will be released in PHP 8.2.4 and 8.1.17.

In the meantime #9364 should provide a userland hotfix.
