I confirm Fons' observation regarding jack2 from AUR (git version), it gives
the same error.
However, compiling jack2 using the package sources from [community]
works. You can retrieve them either via the abs command[1] or manually[2].
Using those package sources together with the -O0 flag got me rid of jack's
undesired behaviour, It's just my guess that your issue might be related.

Don't install anything from source, unless by the usual makepkg/packman tools.
As long as you use provides=(jack`) and conflicts=('jack') in the PKGBUILD,
the locally built package will just replace the precompiled one, nothing needs
to be removed.
