Interestingly, cmake also seems to crash in a similar way: - Log: https://buildd.debian.org/status/fetch.php?pkg=apt-cacher-ng&arch=sh4&ver=0.8.8-1&stamp=1450985460 - Log: https://buildd.debian.org/status/fetch.php?pkg=texworks&arch=sh4&ver=0.5~svn1363-6%2Bb1&stamp=1450992669 - Log: https://buildd.debian.org/status/fetch.php?pkg=x265&arch=sh4&ver=1.8-6&stamp=1450995672 - Log: https://buildd.debian.org/status/fetch.php?pkg=libwebsockets&arch=sh4&ver=1.6.0-2&stamp=1450997039

I am currently in the process of bootstrapping ghc for the Debian sh4 port and ran into a strange problem with qemu-sh4-static which randomly segfaults when running ghc to compile a Haskell source: root@jessie32:~/ghc-7.8.4/utils/ghc-pwd# ls Main.hi Main.hs Setup.hs ghc-pwd.cabal ghc.mk root@jessie32:~/ghc-7.8.4/utils/ghc-pwd# ghc Main.hs /bin/bash: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8) qemu: uncaught target signal 11 (Segmentation fault) - core dumped Segmentation fault root@jessie32:~/ghc-7.8.4/utils/ghc-pwd# ghc Main.hs /bin/bash: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8) qemu: uncaught target signal 11 (Segmentation fault) - core dumped Segmentation fault root@jessie32:~/ghc-7.8.4/utils/ghc-pwd# ghc Main.hs /bin/bash: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8) qemu: uncaught target signal 11 (Segmentation fault) - core dumped Segmentation fault root@jessie32:~/ghc-7.8.4/utils/ghc-pwd# ghc Main.hs /bin/bash: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8) qemu: uncaught target signal 11 (Segmentation fault) - core dumped Segmentation fault root@jessie32:~/ghc-7.8.4/utils/ghc-pwd# ghc Main.hs /bin/bash: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8) [1 of 1] Compiling Main ( Main.hs, Main.o ) qemu: uncaught target signal 11 (Segmentation fault) - core dumped Segmentation fault root@jessie32:~/ghc-7.8.4/utils/ghc-pwd# ghc Main.hs /bin/bash: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8) [1 of 1] Compiling Main ( Main.hs, Main.o ) qemu: uncaught target signal 11 (Segmentation fault) - core dumped Segmentation fault root@jessie32:~/ghc-7.8.4/utils/ghc-pwd# ghc Main.hs /bin/bash: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8) [1 of 1] Compiling Main ( Main.hs, Main.o ) Bad interface file: /usr/local/lib/sh4-unknown-linux-gnu-ghc-7.10.3/time/dist-install/build/Data/Time/Format/Parse.hi ghc: panic!

I have created a tarball which contains the sh4 chroot from the example above which also includes ghc, gcc and the source code in question (in /root/ghc-7.8.4/utils/ghc-pwd). To test, it's probably a good idea to replace the qemu-sh4-static binary in /usr/bin with a current git snapshot (which I tried but didn't help). > http://users.physik.fu-berlin.de/~glaubitz/sid-sh4-sbuild-ghc.tgz In case anyone wants to try ghc with their own sh4 chroot, here's my version of ghc: > https://people.debian.org/~glaubitz/sh4-unknown-linux-gnu- ghc-7.10.3.tar.gz Just extract this tarball into the root directory of the sh4 chroot. Please note, that it might be advisable on sh4 to apply the patches from these two bug reports as otherwise qemu-sh4-static won't work properly on amd64 and misses syscall 186: > https://bugs.launchpad.net/ubuntu/+source/qemu-linaro/+bug/1254824 > https://bugs.launchpad.net/qemu/+bug/1516408 The above issue is reproducible with the two patches applied and without. It's also reproducible with both libc6 2.19 and 2.21 in the chroot. Thus, I am currently out of ideas what else to test.
