Hello --

There is a potential buffer overflow in Phobos's built-in zlib.

The fix is here:
https://github.com/madler/zlib/commit/eff308af425b67093bab25f80f1ae950166bece1

However, that fix broke curl, which prompted a further fix:
https://github.com/madler/zlib/commit/1eb7682f845ac9e9bf9ae35bbfb3bad5dacbd91d

I have a combined diff prepared.
