Uncaught Throwable somewhere in ConcatAnalyzer.php

[ciaranmcnulty]

This line appears to be breaking Psalm for me:
$jsons = glob(__DIR__ . '/../acceptance/**/*.json');

I can't reproduce on psalm.dev but I was able to chop the class down to just that line in a method

I get:

Uncaught AssertionError: assert(count($result_type_parts) === $combinations) in /Users/ciaranmcnulty/Code/dockerfile/vendor/vimeo/psalm/src/Psalm/Internal/Analyzer/Statements/Expression/BinaryOp/ConcatAnalyzer.php:181

This is with:
Psalm dev-master@589fee7b224f4ccb7c878aa3781c38c3a7dbea0a

Fixed in #9351
The fix is released in 5.7.2.

@weirdan I've tried just now with Psalm 5.7.2@9e0dd5ab59498aa3f531bd359bc93dac671c5938 and same error is occurring

[ciaranmcnulty]

Disabling opcache fixed it for me though

[weirdan]

@ciaranmcnulty can you post the error message you're getting on 5.7.2, including backtrace?

I can no longer reproduce now it's successfully run. I'll re-open if it reoccurs
