I modified the test program traps_test.c, this bug should have been fixed.

 

--- Mike Frysinger                                           2010-01-07 22:23:59

ah, sorry about that

 

--- Mingquan Pan                                             2010-01-15 04:00:48

Yeah, this issue goes away now. Close.
