yes I'm trying to run it in gdb, the laptop
freezes for a long time and I have to
restart it, I'll give it more time tommorow
and let it take as much time as it wants

It runs fine for samples/ so we're searching
for a small test case where it trips, so
I'll run it separately for each set of tests,
like benchmarks/ , fstests/ ...

I was building it in a way that the script invokes
covoar multiple times, but Chris' modifications
to covoar added support for reading multiple symbol-sets
after which I changed the coverage script.

If we're planning to have this support in
the python script untill covoar is updated,
then I can add it.
