Actually, looking closer, it appears that lcov is just translating
gcov's textual output into HTML, so that the error is probably to
be blamed on gcc or gcov.  And at least on RHEL, those come from
the same package:

$ rpm -qf /usr/bin/gcov
gcc-4.4.7-18.el6.x86_64

So if you're up2date on gcc, we might have material for a gcc bug report
here.  I'll try to reproduce it on recent Fedora, and if so file something
at Red Hat.
