segmentation fault in sc_core::sc_process_b::semantics

Hi, 

I have a complex design that consists of  multiple static and dynamic (spawned) process. I am getting a segmentation fault in sc_core::sc_process_b::semantics function at run time (probably at time when the method is to be invoked). The back trace is as follows.

Any idea of root cause?  I could not share the design due to its complexity and too many files

Thanks for your help

Dinesh.
