cmprsk- another survival-depedent package causes R crash

As our package developers discussed about incompatibility between Design and 

survival packages,  I faced another problem with cmprsk- a survival dependent 
packacge.

The problem is exactly similar to what happened to the Design package that 

when I just started running cuminc function, R was suddenly closed.

These incidents suggest that maybe many other survival dependent packages 

being involved the problem

  I don't see how this is related to survival.  I just checked the source code 
to the cmprsk function, and it has no dependencies on my library.  As I would 
expect, the cmprks function works as expected on our machines.
  Could you send a reproducable example?
