--- Comment #23 from xur at google dot com --- I overlooked that gcov_master was also used in gcov_dump_int. The bug is exactly as Honza described. I can reproduce with a simple example. Nathan: did you use dlopen? It seems using dlopen will change gcov_master behavior and hide the issue. If you call shared library function directly and use fork, you will reproduce.
