I noticed the same thing. The files available here:
http://geometrica.saclay.inria.fr/team/Marc.Glisse/tmp/cov-bug/
send gcov-4.6 -a into an infinite loop while they crash gcov-4.7 -a (x86_64
debian testing system).

Created attachment 27465
--> http://gcc.gnu.org/bugzilla/attachment.cgi?id=27465
inputs.tar.gz
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).

Just to add on, the issue also happen in gcc 4.4.7 from RHE 6.4. Anyone have
any possible solution or workaround for it? If I disable the all-blocks option,
it will lost the branch coverage data.
Thanks!

I still see this problem in GCC 5.4.0. I am on ubuntu 16.04.12 with lcov
version 1.12 and gcov version is 5.4.0.
This is how it is compiling:
----------------------------
g++ -std=c++14 -DHAVE_CONFIG_H -I. -I.. -fprofile-arcs -ftest-coverage
-DGITVERSION=\"2.2.4-2-gc134167-dirty\" -O2 -Wall -Wextra -pedantic
-I/usr/local/include/ -L/usr/local/lib/ -MT Helper-abc.o -MD -MP -MF
.deps/Helper-abc.Tpo -c -o Helper-abc.o `test -f 'abc.cpp' || echo './'`abc.cpp
With branch coverage enabled the lcov call is freezing
lcov --rc lcov_branch_coverage=1 --directory $PWD --capture --output-file
tests_coverage.info
Only the .gcda file generated for abc.cpp is freezing rest it is ok. I am
literally desparate for some workaround. It's been a long standing ticket not
seen any workaround or fix.

Please update to at least GCC 8.4.0, it should be fixed there.
Older releases are not supported right now.

Thank you @martin. I am not sure whether ubuntu 16.04 is compatible with gcc
8.4.0. Our app. is currently built for ubuntu 16.04 and I don't know what
breaking changes it could bring if we upgrade gcc.
Do you know any workaround other than disabling the whole branch coverage?

I strongly recommend to update to a supported GCC. Note that in the meantime
we've fixed many issues that can theoretically affect your application.

No.
