Summary: Update to zlib 1.2.12
Product: D
Version: D2
Hardware: x86
OS: Windows
Status: NEW
Severity: enhancement
Priority: P1
Component: phobos

Hello --
I've updated the copy of zlib in Phobos.
Here's a reprinting of the big-ticket items from the zlib.net homepage:
Version 1.2.12 has these key improvements over 1.2.11:
* Fix a deflate bug when using the Z_FIXED strategy that can result in
out-of-bound accesses.
* Fix a deflate bug when the window is full in deflate_stored().
* Speed up CRC-32 computations by a factor of 1.5 to 3.
* Use the hardware CRC-32 instruction on ARMv8 processors.
* Speed up crc32_combine() with powers of x tables.
* Add crc32_combine_gen() and crc32_combine_op() for fast combines.
Due to the bug fixes, any installations of 1.2.11 should be replaced with
1.2.12.
Also maintains the fix from here:
https://github.com/ibara/phobos/commit/1b6cf80232f19e581f72869a4b339580416dd72d
Everything appears OK on my OpenBSD/amd64 machine. But perhaps more testing
from others is in order.
