Same here, macOS 13.2; using Docker with php-fpm, I've attached a crash report

Sorry, could you please re-upload that crash report? For some reason it uploaded as an empty file. I have tested attachments on another bug, and it worked without issue.

Doesn't work, not even in a different browser, shall I paste it here directly?

Sigh, I restarted the webserver to apply some updates after testing, and now I see actual errors in the log. Those are fixed.

But you can just email me the files to rsesek @ this domain.

Could you download the report now?

Yes, thank you. For some reason, Apple’s tools are unable to process the report, but I’ve extracted the stack trace:

BUG IN CLIENT OF LIBDISPATCH: dispatch_sync called on queue already owned by current thread

Dispatch queue: org.bluestatic.MacGDBp.MessageQueue.0x6000027d2680 (8)
#1 _dispatch_sync_f_slow

#9 _dispatch_lane_invoke
#10 _dispatch_workloop_worker_thread

But, that is not a ton to go on.

Can you describe when/how this happens, and is this a new problem that just started occurring?

It always happens when I click on "Run", "Step In/Out" works fine, but "Run" instantly causes a crash

Unfortunately I cannot reproduce this. I’ve tried on both an x86_64 machine and an arm64 machine, with the current released build or with local development builds under ASan/TSan/NSZombieEnabled.
