Hi,
I compile program with asan, set ASAN_OPTIONS = disable_core = 0:
unmap_shadow_on_exit = 1: abort_on_error = 1 and run a few hours, the
program may be in a deadlock condition.
if not set ASAN_OPTIONS = disable_core = 0: unmap_shadow_on_exit = 1:
abort_on_error = 1, the program works well.
env:
gcc version 4.9.2 (GCC)
2.6.32-358.23.2.el6.x86_64
