gcov or gcc error

[Margus Metskivi]

Hi

Is there anybody who has a good experience with gcov coverage program? 
Here we have quite a big project with many .so libraries. Someway when 
compiling project files with parameters
-ftest-coverage -f...arcs (or whatever the second parameter for gcov MUST BE)
gcov -b file.cpp doesn't work. file.da, file.bb and file.bbg files are
in the same path with file.cpp but gcov -b file.cpp gives Aborted(core dumped) 
error. Debugging of gcov shows that real count of program "arcs" when executing 
cpp code does not match arc number written somewhere in .bb, .bbg or .da files.
Are there any ideas how to make gcov work?
