.Rationale: This avoids calling an inappropriate overloaded function,
which might expect to be able to modify its argument
. Effect on original feature: Change to semantics of well-defined feature
. Difficulty of converting: Syntactic transformation
. The fix is to add a cast:
char* p = "abc";
void f(char*) {
char* p = (char*)"abc";
f(p);
f((char*)"def");
}
