I'm sitting on this bug for a few weeks, and can thus confirm this also happens also with firefox-98 branch - I felt shy of opening a bug report with a git snapshot of gcc-12 back then.

Now its confirmed with stable gcc-12.1.0

The Bugbug bot thinks this bug should belong to the 'Core::JavaScript Engine' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

At the moment I'm leaning towards a bug in the toolchain, will keep you posted.

gcc devs are convinced it is a binutils bug
