Just FYI, the option --coverage is a short-cut for "-fprofile-arcs 
-ftest-coverage" and furthermore you don't need to explicitly add the 
-lgcov option.

Are you doing fork(2)s in your code?

This sounds like that the application somehow finishes once you return 
to the console. How are you exactly realizing the background thing?

Which version of gcc/gcov are you using?

Is your code complex or could you possible provide it? If possible, 
please don't send it to the mailing list directly, but use some kind of 
file hosting (e.g. http://uploaded.to).
