This is because such memory could be treated as available in the child given that the threads it related to do not exist in the child, and consequently the processing performed in the child before <i>fork</i>() returns could make use of that memory. Therefore applications should avoid using in the child any pointers to thread-specific memory that were passed to the calling thread from other threads in the parent.</blockquote> Issue History Date Modified Username Field Change ====================================================================== 2017-01-12 16:05 Florian Weimer New Issue 2017-01-12 16:05 Florian Weimer Name => Florian Weimer 2017-01-12 16:05 Florian Weimer Organization => Red Hat 2017-01-12 16:05 Florian Weimer Section => fork 2017-01-12 16:05 Florian Weimer Page Number => unknown 2017-01-12 16:05 Florian Weimer Line Number => unknown 2017-01-12 16:50 torvald Note Added: 0003541 2017-01-12 16:50 torvald Issue Monitored: torvald 2017-05-19 20:20 slow Issue Monitored: slow 2017-10-30 16:35 Florian Weimer Issue Monitored: Florian Weimer 2018-07-19 15:20 geoffclare Note Added: 0004054 2018-07-19 15:22 geoffclare Note Added: 0004055 ======================================================================
