@yf13 yes apparently getprogname() was the only reference from children threads to the group argument vector, so maybe I'm just foaming about nothing. Why I started foaming: It made no sense to me that the threads of a process could not access the process argument vector but this is just nonsense; the program can always make a local copy or reference for them (in case of just making a reference it would cause the same crash as getprogname did previously; the parent stack / TLS is simply released too soon). Making getprogname() to work from pthreads is quite simple, just make a const char * reference to TLS and point the parent argv[0] to it (making sure the string is NOT released before the process itself has completed / fully exited). In kernel mode it's even easier, you don't need TLS just declare something similar to __thread instead (as every process has its own address environment). -- This is an automated message from the Apache Git Service.
