Re: bug in ghc 9.6 ?

[Gianfranco Costamagna <locutusofborg@debian.org>]

Hello, I don't have an answer, nor I do speak haskell, but hkl has been segfaulting during build (s390x only) with older ghc in Ubuntu,
and so far I couldn't find any reason/fix for that issue

https://launchpadlibrarian.net/745152493/buildlog_ubuntu-oracular-s390x.hkl_5.0.0.3462-1build1_BUILDING.txt.gz

make[4]: *** [Makefile:833: binoculars-ng] Segmentation fault (core dumped)

I  tried some approaches, to call cabal manually, but none worked (even disabling optimization) and qemu-s390x is not able
to allow me to gdb it...

Maybe new ghc spotted the bug in Debian too, while older one was just segfaulting under some particular optimization arch.

Hello I am preparing the hkl package whcih contain an haskell program (binoculars-ng)

when I try to recompile it with ghc 9.6 on Deban unstable I get this error message.

[35 of 35] Compiling Hkl              ( src/Hkl.hs, /home/picca/src/repo.or.cz/hkl/binoculars-ng/dist-newstyle/build/x86_64-linux/ghc-9.6.6/hkl-0.1.0.2/build/Hkl.o, /home/picca/src/repo.or.cz/hkl/binoculars-ng/dist-newstyle/build/x86_64-linux/ghc-9.6.6/hkl-0.1.0.2/build/Hkl.dyn_o )

  GHC version 9.6.6:

CallStack (from HasCallStack):

So my question is how can I help solve this issue ?
