You are ignoring the fact, that objects, loaded at the application startup time are getting searched first, followed RTLD_GLOBAL objects, and finally by the loaded object DAG. LD_PRELOAD objects override them all. > > First strong/last weak should win. You are saying "last weak" is not > winning. That's a linker bug. If last weak will win, the normal case when Xthrstub is loaded _after_ libc_r will break. The only way to really fix this is to export pthread_ symbols as strong in libc_r. Exporting them as weak sounds like is a mistake which should be fixed. -- Alexander Kabaev To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
