I'm also seeing this on m68-elf.

It appears to have been caused by the following patch (r106804)

Or perhaps the patch that tightened operand checks for "g".

Maybe. Reverting r106804 seems to fix the problem.

Please open a PR with preprocessed source attached and assign it to me.

This is now PR24912
