It is built using g++ -g pthread_test.cpp -lpthread The version numbers are $ cat /proc/version Linux version 2.6.21-1.3228.fc7 (kojibuilder@xenbuilder2.fedora.redhat.com) (gcc version 4.1.2 20070502 (Red Hat 4.1.2-12)) #1 SMP Tue Jun 12 15:37:31 EDT 2007 and gdb snapshot for July 24th $ gdb --version GNU gdb 6.6.50.20070724 Below is the log of gdb session $ gdb a.out GNU gdb 6.6.50.20070724 Copyright (C) 2007 Free Software Foundation, Inc.
