It's from rev 525 compiled on debian (but buildtag was set to 'ubuntu') with -o0 switch, unstripped binary. POL sometimes crash randomly after few minutes after start, without players online or when i'm trying to wipe area from npcs.
I've tried to switch ai scripts to dummy ones with "return 1;" or empty "while (me) sleep(2 minutes) end" loop. No luck here. What i've found that the same data files run on 32 bit rev 525 compilation under windows are working just fine. I can wipe whole world from npcs and no crash here. But under linux it keeps crashing randomly on 64bit and 32bit binaries. I've tried running pol under debian and slackware 13. Debian was installed on vmware with 4 GB of ram and slackware is old pc box with p4 3,6Ghz HT and 4 GB of ram.
I've already tried to revert scripts to one of my old backups but no luck either. I've noticed that when i delete npcs.txt and npceqip.txt POL works fine. I can also leave npcs alone and delete storage.txt and POL will work w/o crash. But that's not an options as i want to keep my worldstate intact.
