string signal segmentation fault

string signal segmentation fault

[Karl-Heinz Mali]

Hi

How can I solve the following problem with the signal segmentation fault 
runtime error under SuSE Linux 8.2 with g++ (gcc) 3.3-23. What is wrong with 
the constructor string operation _sMergeMin = _sMergeMax = ""; after the 2nd 
instantiation of the template Record<T> db; in a loop? The code is not 
multithreaded.

Tanks
