Summary: The NetBSD specific implementation of cxa_atexit() does not preserve the 2nd argument if dso is equal to NULL. Changes: - Split paths of handling intercepted __cxa_atexit() and atexit(3). This affects all supported Operating Systems. - Add a local stack-like structure to hold the __cxa_atexit() context. atexit(3) is documented in the C standard as calling callback from the earliest to the oldest entry. This path also fixes potential ABI problem of passing an argument to a function from the atexit(3) callback mechanism. - Add new test to ensure LIFO style of atexit(3) callbacks: atexit3.cc Proposal to change the behavior of __cxa_atexit() in NetBSD has been rejected. With the above changes TSan/NetBSD with the current tsan_interceptors.cc can bootstrap into operation.
