9 I just rebuilt my system for ~amd64 and have it working fine. The thing to
10 understand about Acrobat Reader is that it has forever been linked
11 incorrectly: it contains both an embedded old zlib AND dynamically links
12 against the system-wide zlib version. Yes, these people are laughably
13 incompetent.

15 This goes poof when e.g the dynamically loaded zlib is compiled with -O3,
16 which seems to change symbol entry points & offsets. If I had to look
17 deeper that would be my first angle of attack. Since I now have the
18 x86-emul-libs prebuilt I no longer have this problem; however on my
19 remaining 32bit x86 installation zlib must still be built with -O2 only.
