macOS: reliable crash on debugging #76

Open poke1024 opened 6 years ago

poke1024 commented 6 years ago

On macOS, Krom always crashes for me when started from inside Kode Studio and then quitting (i.e. Krom crashes when closing its window/closing the app).

I didn't manage to get a crash report/stack trace for this (though trying hard).

The reasons seems to be debugging. If I disable debugging by removing '--debug', port.toString() from the launch command line in KodeStudio.app/Contents/Resources/app/extensions/krom-debug/out/chromeDebugAdapter.js, things work fine.

Also, strangely, if I run with debug flags from the command line with some bogus port (e.g. mykrom/macos/Krom.app/Contents/MacOS/Krom myproject/build/krom --debug 8080), there's no crash on quitting Krom.

The main annoyance with this is that macOS will ask on every new start of Krom, if you really want to launch it, as it crashed last time.

Finally produced a stack trace:
