Charm++ parallel programming system

Sir:
     Thank you! :-) I've fixed that problem.

     But a new one occurred: 

------------- Processor 0 Exiting: Caught Signal ------------
Signal: segmentation violation
Suggestion: Try running with '++debug', or linking with '-memory paranoid' (memory paranoid requires '+netpoll' at runtime).

Fatal error on PE 0> segmentation violation

I ran the simulation like this:

../tmp/charmrun +p1 ../tmp/bigemulator 1 0 ++remote-shell ssh

I debugged the program, and I found that this error occurs at line 234 in evq.C, where it seems that POSE is trying to delete an Event, during which it has to delete the corresponding message ---- "msg". The error occurs when the program is trying to enter the deconstructor of "msg", I mean it seems that the address of the deconstructor of "msg" is invalid. 

How should I deal with it, what kind of bug in my code can lead to this error? Please help me, Thank you very much:-)
