Subject: Don't dereference invalid iterator in wxDateTime::ParseDate().
X-Git-Url: https://git.saurik.com/wxWidgets.git/commitdiff_plain/462f4f19b5e20055a59ca93cdc19094552a416f1

Don't dereference invalid iterator in wxDateTime::ParseDate().

If the string passed to this method contained only spaces (possibly 0 of them,
i.e. was empty) we would dereference the end string iterator. Fix this by
adding an explicit test for "p != pEnd".
