Hi, i'm using +- latest rAmod (did't apply last 2 commits only)

I need to understand, what is provoke server to crash by this core dump output, and i can't understand.

 

Here is core dump output step by step. Who understand in this code, help me please to understand where is a problem what make map-server crash.

 

step 0

Source Code from this part:

379		ud->walk_count++; // Walked cell counter, to be used for walk-triggered skills. [Skotlex]
380		status_change_end(bl, SC_ROLLINGCUTTER, INVALID_TIMER); // If you move, you lose your counters. [malufett]

Help me please, understand what is wrong, what did provoke to crash a map server?

Thank you very much!
