Uninitialized string offset -1 at Psalm/Internal/Fork/PsalmRestarter.php:90

[oddnoc]

psalm 5.7.6 crashes when psalm is invoked on the command line. This did not happen in 5.7.5 or earlier.

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

[oddnoc]

It happens before any code is analyzed, so I'm not sure how to test it on psalm.dev.

Here is the entire transcript, with long disk path redacted:

@oddnoc can you run the following:

php -r 'var_dump(ini_get("opcache.jit_buffer_size"));'

and report the output here?

[weirdan]

Anyway, I think #9397 should solve this.

[oddnoc]

php -r 'var_dump(ini_get("opcache.jit_buffer_size"));'                                                              [8.0.28]
Command line code:1:
bool(false)

PHP is v8.0.28

[weirdan]

It should be fixed in 5.7.7, released moments ago.

[aboyton]

Thanks for the fix. I can't seem to see 5.7.7 in https://packagist.org/packages/psalm/phar but I can for https://packagist.org/packages/vimeo/psalm. Any chance you can release a .phar version as well?

[weirdan]

Due to how psalm/phar releases are published, fixing missing 5.7.7 would be tricky. I released 5.8.0, which also includes this fix - it's already available through all distribution channels.
