I have a function with a prototype like the following:
void function(std::string str);
This function is called in my main function in another program that loads and uses that dll.
function("some string value here");
When returning from this function I get heap corruption error:
Windows has triggered a breakpoint in program.exe.
This may be due to a corruption of the heap, which indicates a bug in program.exe or any of the DLLs it has loaded.
This may also be due to the user pressing F12 while program.exe has focus.
The output window may have more diagnostic information.
Playing around with my code I noticed a few strange observations:
1. When length of the string passed in is less than 11 characters I get no errors, as soon as I add more characters the error appears.
2. When changing the type of parameter from std::string to std::string& the error disappears. The idea of passing reference came from here.
3. I've commented out the body of the function. The operations in there have nothing to do with the exception produced.
4. Changing parameter type from std::string to char* also solves the problem.
What could be causing this error? How do I solve it?
