See PR bootstrap/55051 for a discussion of why this is occurring and why this checking is inaccurate. Leave it in when !GCOV_LOCKED, to warn about concurrent update issues requiring locking. 2012-11-18 Teresa Johnson PR bootstrap/55051 * libgcov.c (gcov_exit): Remove merged program summary comparison unless !GCOV_LOCKED.
