Revision 1.1, Tue Mar 5 01:35:52 2019 UTC (5 years ago) by christos
Transfer all the keys that were created in the libc stub implementation to the pthread tsd implementation when the main thread is created. This corrects a problem where a process created keys before libpthread was loaded (either from the libc constructor or because libpthread was dlopened later). This fixes a problem with jemalloc which creates keys in the constructor. |
