Release tag v22.03.123 mangosd core dump on Linux

[begemotik]

Hello, community!

After compilation of v22.03.123 on Ubuntu 22.04 there is core dump with Playerbots enabled.

And it's all OK with Playerbots disabled.

How to resolve this issue?

Is this issue solved? Or its wrong?

File: server/src/modules/Bots/playerbot/PlayerbotAI.cpp

Function: bool PlayerbotAI::CastSpell(uint32 spellId, Unit* target)

Error RowNum: 1343

To resolve we need to delete double "delete spell;" instruction?

    if (!bot->IsInFront(faceTo, sPlayerbotAIConfig.sightDistance, CAST_ANGLE_IN_FRONT) && !bot->IsTaxiFlying())
    {
        bot->SetFacingTo(bot->GetAngle(faceTo));
        spell->cancel();
        delete spell;
        SetNextCheckDelay(sPlayerbotAIConfig.globalCoolDown);
        delete spell;
        return false;
    }

In current master branch this issue exists too!

Hi begemotik,

I was talking with someone on our Discord channel who has been arm's deep into the MaNGOS Zero playerbot code, and he concurs with your observation that it is likely a fragment of a merge.

Try deleting one of the calls, and then rebuild your mangosd binary/executable.

Let us know how that goes! If it works out, then you can submit that as a commit to the codebase  

 

Thanks!
