The reason is an obscure bug in gcc that only triggers when accessing
exactly the 32767th element of a character array. Since I don't know
how fix it in gcc and nobody else seems to be working on that, I
suggest you apply the following workaround:
--- writezip.c~ 2007-04-15 14:12:19.000000000 +0200
+++ writezip.c 2007-04-15 14:12:39.000000000 +0200
