The submitter's testcase works if function __gcov_init in libgcov.c
is declared hidden. Probably all of the __gcov* symbols ought to be
hidden; I'll work on a patch to hide that symbol and others that seem
appropriate.
Possible workaround:
The linker's -E option exports all global symbols from the executable
to the dynamic symbol table. A subset of global symbols can be
exported by using -E along with --version-script to list symbols to
export. Depending on how many symbols a shared object needs to access
from a shared object, this might be a reasonable workaround.
I consulted an expert, and unfortunatly there doesn't seem to be a way
to say "export all symbols except this small list".
