>Description:
GCC correctly gives an error when trying to strcpy into a "const char *" pointer. But GCC incorrectly allows a strcpy into a "const char * const" pointer as shown in the code below.
>How-To-Repeat:
#include <string>
int main()
{
const char * source = "source";
const char * const target = "target";
std::strcpy(target,source);
return 0;
}
>Fix:
//make the target pointer non-const:
#include <string>
int main()
{
const char * source = "source";
const char * target = "target";
std::strcpy(target,source);
return 0;
}
