Seems like you're good for a bug report to the upstream project. I
checked their Git repo, there is a gcc 4.9 fix but specific for ARM
issues. I haven't seen any other commit mentioning "4.9".

You may want to try with their latest Git version first, though, just
in case the problem was fixed but not mentioned explicitly in a commit
log.

Best regards,

Thomas
