[Resending because previous attempts did not register in RT]

Freeciv 2.0.0-beta1 crashes for a small world with a large fraction of
landmass, because of an assertion failure:
civserver: temperature_map.c:78: create_tmap: Assertion `temperature_map
== ((void *)0)' failed.

This is the stack trace:
#3  0x400a8b3f in __assert_fail () from /lib/libc.so.6
#4  0x0813b9f8 in create_tmap (real=false) at temperature_map.c:78
#5  0x08138058 in initworld (pstate=0xbffff6e0) at mapgen.c:1623
#6  0x08138250 in mapgenerator2 () at mapgen.c:1690
#7  0x08136409 in map_fractal_generate (autosize=true) at mapgen.c:1029
#8  0x080515c0 in srv_loop () at srv_main.c:1775
#9  0x080511cf in srv_main () at srv_main.c:1622
#10 0x0804a8fb in main (argc=3, argv=0xbffffa34) at civserver.c:167

Attached is an autogame that reproduces the problem for my computer
(Debian GNU/Linux sarge, gcc 3.3.5). Note that I complied after
configuring with CFLAGS="-O0 -g".
