Description Enrique 2010-09-12 02:01:33 UTC 
Created attachment 446712 [details]
Simple use of ltopen/ltclose

Description of problem:

  Using the dlopem/dlclose mechanism leads to a memory leak detected by valgrind. I attach a code snippet.

How reproducible:

 Always. 

Steps to Reproduce:
1. Compile the code snippet:
      g++ -o lt lt.cpp -ldl
2. Run valgrind:
      valgrind --leak-check=full --show-reachable=yes --trace-children=yes ./lt
3. Check the valgrind report ("still reachable: 56 bytes in 1 blocks")
