RE: Invalid use of const pointer?

Regarding: “This Thanks mostly goes to Joe Filion who initally noticed this.”

 

Your welcome.

 

If interested, I found another similar construct in another area of the code. Don’t worry, this appears to be the last one.

 

On line 557 of implicit.c:

 

                  p = strchr (nptr, '%');

 

nptr is a const pointer, but p is used as a non-const pointer later on and modifies the string.

If so, the easy and more correct fix might be to to remove const from the

function variable declarations rather than to restore the value.

This Thanks mostly goes to Joe Filion who initally noticed this.
