[Bug gcov-profile/35038] GCOV - using "--coverage" results in libgcov.a(_gcov.o) is referenced by DSO

["nanda dot anni at wipro dot com" <gcc-bugzilla at gcc dot gnu dot org>]

------- Comment #1 from nanda dot anni at wipro dot com  2008-01-31 04:47 -------
I am unable to proceed further to get the code coverage for my application
(product).
Hence it is critical to fix this issue.
I had posted a query to gcov maintainers but their response was that, there
might be a bug in gcc itself. Hence reported this bug.

Try using -fprofile-arcs as linker option instead of -lgcov. If that doesn't
help this is most likely a bug in gcc. Please report to the gcc maintainers.
