I used  set <string> ss 
as a containtor for a list of unique, ordered strings. However, program
reports segmentation error when trying to allocate a block of memory. 

I have used libcwd to debug the memory allocation, the libcwd detected
memory leaks:

|MALLOC  : operator new (size = 1088) = 0x83a2a18                             |

|  * WARNING : Memory leak detected!                                          |

+-----------------------------------------------------------------------------+

Memory leak problem solved by changing 
Set <string> ss  ==>   set <char*> ss
However, I'm not sure if this only solves the problem temporary, since
set <string> does not result in memory leaks in most cases. 

Program was compiled by  
g++ -g3 src.cpp  -o prog -lm
