I'm seeing very similar behavior running gcov on the attached files
(inputs.tar.gz contains utility.gcda and utility.gcno).

"gcov utility.gcda -b -c -a -p" hangs indefinitely (at least, it ran for 24
hours before I killed it)

"gcov utility.gcda -b -c -p" returns in less than a second.

This is using Fedora 16's build on an x86_64 system (gcc-4.6.3-2.fc16.x86_64
RPM).
