Please also include emerge --info if not already working on it.

Anyway, this is because of -Og. It's a valid bug that should be sent upstream (could you do it please?) but it's quite common when people use always_inline incorrectly.

Thanks, trying with -O2
An upstream ticket already exists on this matter (#19776), and resolved by pull request #20562, didn't try this patch.
