Automoc hanging for some FreeBSD users

[Raphael Kubo da Costa]

Hi all,

Some FreeBSD users who use -CURRENT (the unstable version) have been
experiencing some problems while compiling the KDE ports.

automoc seems to hang at random points during compilation. I asked one
of the users for a backtrace, and it follows below. I'm still clueless
and don't know for sure if it's something on our side or it's due to
some FreeBSD bug on libc, for example.

Has anyone ever experienced something like that before?
