Package: gcc-4.9 Version: 4.9.0-6 Severity: normal Dear Maintainer,
since 4.9, the simgrid package sometimes FTBFS with the following error on various architectures: lto1: fatal error: LTO_tags out of range: Range is 0 to 368, value is 756 This may be related to the fact that we build with gcc-ar and gcc-ranlib instead of ar and ranlib. We do that because we have a static library factorizing some code between out test cases, and cmake makes it uneasy to share the .o in another way. The strange thing is that this bug does not seem to occur all time, and appears on various architectures. Some builds leading to that bug: https://buildd.debian.org/status/fetch.php?pkg=simgrid&arch=powerpc&ver=3.11.1-5&stamp=1403865151 https://buildd.debian.org/status/fetch.php?pkg=simgrid&arch=armhf&ver=3.11.1-5&stamp=1403865694 On armhf, it did build correctly 4 times before that failed build, for versions 3.11.1-1 to 3.11.1-4. The changes between these version is completely unrelated to armhf, I think. On kfreebsd, it worked with LTO enabled here: https://buildd.debian.org/status/fetch.php?pkg=simgrid&arch=kfreebsd-amd64&ver=3.11.1-5&stamp=1403865120 but failed here: https://buildd.debian.org/status/fetch.php?pkg=simgrid&arch=kfreebsd-amd64&ver=3.11.1-2&stamp=1403119800 (versions in between were broken on kfreebsd because of our usage of java, ignore them) I tried to disable the parallel building of the simgrid package, in vain. Do you guys have any idea about what's going wrong, please?
