Welcome to GSoC! You are now in new territory. :)
Dig in and see what went wrong. Be aware.that GCC file formats may (or may
not) be subject to.changing over time and this could just be bitrot.
Gcov-dump is installed with the compiler.
You should check it we have a .h file describing the file and it is out of
date.
Also I think we now should bring the gsov maintainer in.
Good job!
