That's strange, and makes me suspicious something more isn't afoot here. 
Sadly for me (on Fedora 17, clang 3.0) clang crashes during the build of 
p11-kit, so I can't duplicate this.

Obviously such an intermittent bug could also be use of uninitialized 
memory. But valgrind shows nothing of the sort.

Will look into it further...
