Are you attempting to modify the strings using the pointer returned by c_str()? If so, DON'T! Otherwise, normally, calling c_str() several times should not cause a memory leak or cause your program to crash. Have you tried looking at the stack trace to see where it is crashing?

So far I have managed to compile and link the program with little modifications in the source code, mostly by replacing the .data() with .c_str() method. The main program consists of the for() loop which iterates through the file list, and applies some calculations to the files data. After the changes I've made the program completes only one full loop run, the second run almost always ends up with "Bus error" or "out of memory" error, all in the random places of the loop. Does anyone know if std::string might not entirely free the used resources, or do I have to look for something else to blame? I am looking for some function to display the free memory, perhaps that would give me any idea what goes wrong in the program, unfortunately I cannot find any. Can you give me some hints? I am working on SunOS 5.8 with gcc++ 2.95.3. Thanks, Krzysztof -- Krzysztof Wisniowski | Siemens Sp. z o.o. ICM N&S SDC NE 3 | Software Design Center Phone: +48 71 799 2403 | 54A Strzegomska Str.
