Description of problem: The build tends to hang on executing the following step: + ./waf configure --mandir=/share/man/man1 --libdir=/lib64 --doxygen --dbus --classic --firewire --freebob --alsa Version-Release number of selected component (if applicable): jack-audio-connection-kit-1.9.7-2.fc17 Steps to Reproduce: 1. koji build --scratch f17 'git://pkgs.fedoraproject.org/jack-audio-connection-kit?#HEAD' Actual results: http://koji.fedoraproject.org/koji/taskinfo?taskID=3419311
Are we sure this is a bug in the package but not in the compiler? It seems to hang in the tests run by the configuration script. Moreover, it seems to not hang on x86_64. I have to take a closer look though.

The fact that it passed on x86_64 in Koji must have been an accident.

That was my initial guess since it hangs in the beginning of the waf commmand. It most probably invokes the compiler (gcc) for its tests the same way when you the "configure" scripts do in autotools projects. I'll take a look when I get a chance. So far, the only difference that I know between F-15 (where it doesn't hang) and F-17 (where it hangs) is - python-2.7.1 -> 2.7.2 Is there any other significant change that you know? > > Moreover, it seems to not hang on x86_64. > > I tried it 8 times on x86_64 and it always ended up hanging. The fact that it > passed on x86_64 in Koji must have been an accident. Interesting. Here on my computer I am lucky enough to have accidents whenever I try then.

If I run the build in mock on a RHEL-6 host using the same mock profile, it hangs. I wonder if the problem is triggered by the difference in kernels being used.
After some F-16 update, I started observing the hang on my box too. I tried passing a '-j1' argument to 'waf configure' and it stopped the hanging on my side, also on koji. I am marking this workaround as a fix. Please reopen if you find a better fix.
