Hi all,

Please reference this forum thread - https://bbs.archlinux.org/viewtopic.php?pid=816770 And this submitted bug report - http://bugs.archlinux.org/task/20647

Basically, the PKGBUILD for lib32-zlib has CFLAGS=${CFLAGS/-O2/-O3}, which is meant to remove optimization flags. What it does though is remove the -O2 flag and add an -O3 flag, causing the segfaults I ran across.

Does it work when you build OpenSong from source ? lib32-gzip seems to pass all tests, it might be some sort of binary incompatibility ? It has no problems running in Valgrind.

By the way, could we have in [multilib] the attached valgrind-x86 package or some modification of it ? The default valgrind only support x86_64, I'm not sure whether it's enough to just ship the missing files like I do (a split valgrind package would probably be best).

Not really possible to build from source, it uses RealBasic and I have no idea how to use it, plus its 30-day trial and all that. I'm just thinking there's a reason zlib is supposed to be compiled without optimizations (as shown in the current PKGBUILD), just that the line shown doesn't work as intended =)
