[R] cmprsk- another survival-depedent package causes R crash

[Terry Therneau]

> 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?
