it looks like bug in clang compiler. If i compile with standard options and=
DEBUG_FLAGS=3D-g then it crashes:
bt
0: kill() from libc
1: __stack_chk_fail() from libc.so.7
2: __stack_chk_fail() from libc.so.7
3: swap_on_off() swapon.c:249
4: main swapon.c:186
If i compile it with -O0 -g then it do not crashes.
