[Dastgir 1246]

Like which monster you doing @mi,

And gdb report would help to solve your problem.

ok, thanks for your reply @Dastgir.

 

i've tested on random monster id and name but all caused map-server crash and this is my GDB result on map-server crash when using "@mi poring' command.

According to gdb , 5274 must be inside mobinfo command with "sprintf" function,

Maybe you updated your repo after crash??

If so, please recompile, get the gdb report, and the line menioned on gdb report.

please do what dastgir recommend and please recompile it with debug mode specify so that we can see more detailed information..

./configure --enable_debug

 

[komisaris 0]

i've

 

 please recompile, get the gdb report, and the line menioned on gdb report.

 

i've recompiled the server with --enable-debug=gdb , but  how to get that report you mentioned

 

like these?
