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).

FWIW, I see the exact same problem with Daniel's test program:

$ gcc -c test.cpp
test.cpp:8:2: error: stray ‘#’ in program
 BROKEN
  ^
test.cpp:8:27: note: #pragma message: message0
 BROKEN
   ^
test.cpp:8:3: error: ‘pragma’ does not name a type
 BROKEN
   ^

Note that this is with gcc 4.9 (at least, RedHat's version of it, as packaged
in Fedora 21):

$ gcc -v
