Mysterious warning

I just added some fairly old C++ lex/bison code to my app, code that has been in use for a long time elsewhere and works fine. My app is compiling with much stricter warnings than many of my other projects though, and this line is throwing a warning:


	lvalp->val = strtod( --wptr, &wptr );

"warning: operation on 'wptr' may be undefined"

wptr is declared:

	static   char*	wptr = NULL;

Can anyone shed any light on what's wrong here? Hopefully the above is enough to go on.

tia,

Graham
