I receive a segmentation fault when I launch geocache_seed:

(gdb) run -c /etc/mod_geocache/geocache.xml -t mtb-cartography -z 0,2 -n 4 Starting program: /usr/bin/geocache_seed -c /etc/mod_geocache/geocache.xml -t mtb-cartography -z 0,2 -n 4 [Thread debugging using libthread_db enabled]

Program received signal SIGSEGV, Segmentation fault. 0x0000000000000001 in ?? () (gdb) bt

I'm using mod-geocache 0.3.1 on CentOS 5.5

Looking into the source it seems that the log method was not bound to the gctx struct, yet.

Looking at the code, this has been fixed in trunk. I don't have the time to backport this in the 0.3 branch until next week, I'll release a 0.3.2 then (there's another critical fix that should be addressed in the seeder too, see r261).

After commenting the line of code, that caused the error described above, I received the folloing segmentation fault:

does the segfault also occur in trunk ?

Tryed the trunk version from today morning and it worked without segfault error using 4cores.
