When a thread calls dlclose its thread_local variables are destroyed, but if there are other threads with thread_local variables the DSO is kept in memory until those variables are destroyed (when the threads exit or call dlclose). https://sourceware.org/glibc/wiki/Destructor%20support%20for%20thread_local%20variables -- You are receiving this mail because: You are the assignee for the bug.
