In the statements
char * str = "abc";
str = "xyz";
is malloc or one of its relatives used for the memory allocation
I assume that there is no memory leak when these statements are executed.
Does the system use free(...) before reallocating the memory
If one needs to release the allocated memory some time before the execution of the second statement, can one use free((char *) (str-1));
Thanks.

Calling free in these circumstances does not seem to cause a crash or raise an exception, but I am using MS VC++ Version 6. Perhaps later versions of C++ are less tolerant.

Calling free on str would cause the program to either crash or raise an exception as the address passed to free would not be a valid dynamic memory address.
