Hi,
When using plfill with arrays with too many elements, the number of
elements used gets reduced to PL_MAXPOLY. If the values of the last
elements are not equal to the first elements the number of elements is
increased and the arrays will be written beyond their bounds. The
bound_overflow patch fixes this issue.
c_plfill3 seems to have the same problem seems to have the same error
(plfill.c:127), I've no test case for it so didn't fix it. Should I post
a bug report or can you fix it quickly?
Regards,
Mark de Wever
