--- Comment #5 from John Paul Adrian Glaubitz <glaubitz at physik dot fu-berlin.de> --- Hello! Just as a heads up: This particular problem did not occur with the snapshot as of 2014-12-20 (r218987) and we actually always built gdc in Debian. So it's definitely a regression as a result of the various changes to the SH target since r218987 as we discussed earlier. This problem affects gcc-4.8 and 4.9 and can be avoided by disabling the gdc package. We have currently disabled gdc in gcc-4.9 and 5 which results in gcc-4.9 being built (gcc-5 is still not being built for known reasons). But it _seems_ that this particular bug shows itself now when trying to build gcc-4.9 as the compiler reproducibly segfaults now [1]. I still have to confirm this by trying another buildd, but I have the suspicion that this segfault is directly related to the aforementioned regression. If this is actually a bug, building gcc-4.9 on tirpitz should fail within approximately an hour. I will report back then!
