I'm willing to bet this is a duplicate of 61033 that also involves a qmltextgenerator.ii preprocessed reproducer file ;)
It goes into an infinite loop for me on arm-none-eabi with 4.9 and passes with current trunk. Didn't try 4.8, I expect it fails there like you say.
I don't remember if it was fixed in trunk and the fix not backported or just made latent.
