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 |
|libstdc++.so.5:_ZNSt24__default_alloc_templateILb1ELi0EE14_S_chunk_allocEjRi]|
| * WARNING : Memory leak detected! |
| * 0x83a2a18 std::__default_alloc_template<true, |
| * 0>::_S_chunk_alloc(unsigned int, int&) <unknown type>; (sz |
| * = 1088) |
+-----------------------------------------------------------------------------+
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
