pthread app under debugger has __nptl_create_event int3 copied into code cache #490
From bruen...@google.com on June 08, 2011 08:30:50
the __nptl_create_event routine, AFAICT, is used as part of the
interp: start_pc = 0x00007f21ada9e483
Program received signal SIGTRAP, Trace/breakpoint trap.
(gdb) x/5i 0x00007f21ada9e483
(gdb) disas __nptl_create_event
this is inside libpthread.so.0

Yes this is an annoying feature caused by GDB, I have seen many times whenever debugging a multithreaded application. Better document it somewhere.
