[Pkg-gauche-devel] Bug#766639: gauche: FTBFS on ppc64el (and maybe ppc64)

Frederic Bonnard frediz at linux.vnet.ibm.com
Fri Oct 24 15:06:55 UTC 2014 

Package: gauche
Version: 0.9.4-3
Severity: normal
Tags: patch
User: debian-powerpc at lists.debian.org
Usertags: ppc64el

Dear Maintainer,
we saw that gauche doesn't get compiled on ppc64el because gosh hangs in a futex.
https://buildd.debian.org/status/fetch.php?pkg=gauche&arch=ppc64el&ver=0.9.4-3&stamp=1414085994
and
https://buildd.debian.org/status/fetch.php?pkg=gauche&arch=powerpc&ver=0.9.4-3&stamp=1410804116

I had it working all the time in a ppc64el UP chroot. I guessed it's something to do with threading.
Here is a sample backtrace when "gosh" hangs :

So it's stuck in libgc code.
In gauche 0.9.3, gc is 7.2 and in 0.9.4 it's 7.4.
Between 7.2 and 7.4, it seems PARALLEL MARK has been enable by default in libgc for the 
powerpc build :
https://github.com/ivmai/bdwgc/commit/9f60d6792c135fb7638f4b74ceaded4afd1f1fcf
and it seemed to be tested on powerpc at that time but disabling it, enables gosh not
to hang..
So in the meantime here is a patch to disable PARALLEL MARK on powerpc builds (though I could test it on ppc64el only)
Hope that helps,

F.
