Public bug reported:
Hello!
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:
address@hidden:~/ghc-7.8.4/utils/ghc-pwd# ls

As seen above, compiling a Haskell source code often results in a
segfault but simply by retrying to run ghc over and over again, the
compile process will eventually succeed and no segfault occurs.
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.
Cheers,
Adrian
