OK, I was thinking the error was in the function prototype, after all that was what was given, however it is further down (rusty!):
Code:
              {
              char *tmp; 

              if ((tmp = strchr(dest,'/'))) {
                tmp[0] = '\0';
                instance = tmp + 1;
              }

Specifically the tmp assignment.

The phenomena is explained here by the looks... GCC 4.4 Release Series — Porting to the New Tools

Corresponding to each Panel-creation function (see plbutton(2)) is a function that reinitializes the parameters of that kind of panel. The reinitialization functions are all named by inserting the string init after the creation function's initial pl. For example, plinitbutton will reinitialize a panel created by plbutton. Their argument lists are identical to the corresponding creation function, except that the first argument is a pointer to the panel to be reinitialized, rather than its parent. SOURCE
