--- Comment #6 from Zaak <zbeekman at gmail dot com> --- Oh, I see, so the *bug* has been backported... sigh. Well thanks for localizing it to the range r243909-r244868. I may try to do a bisection search to find the culprit and work up a fix/patch... I haven't contributed to GCC before though, if I need to sign a CLA, etc. please point me in the right direction.
