From 8d92e32a73655a0820ce5085f017911abaad28b3 Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Tue, 28 Apr 2015 11:07:24 +0800 Subject: init.c (__nptl_initial_report_events): New variable. (__pthread_initialize_minimal_internal): Initialize pd->report_events to that. This patch helps NPTL report TD_CREATE event, so that GDB could catch the event and update its thread_list.
