I compiled openttd (r16415) with the enable-dedicated and without-zlib on sparc/gentoo. When i'm try to download some content the game crashes with the following error messages:

Downloading 8 file(s) (213566 bytes)
Error: NOT_REACHED triggered at line 347 of /home/eod/openttd/svn64/src/network/network_content.cpp
openttd: /home/eod/openttd/svn64/src/openttd.cpp:118: void error(const char*, ...): Assertion `0' failed.

Imho there should be a warning/error-msg which says that content system is not available if openttd has been compiled without zlib, instead of crashing :)

ps: i have to compile openttd without zlib, but that's a different story
