Problem - possible Race condition in macroquest or plugin and DataTypeTemp(MQ2DataTypes.cpp)

[winnower]

Not sure where to post this..

It looks like something like
/varset foo ${String[foo].Replace[OR,||]}
is evaluating as
/varset foo ">> "

I believe there is a possible race condition in the use of the global variable DataTypeTemp. Is there possible some plugin that starts it's own thread which accessing DataTypeTemp?

This problem is pretty rare, like I can do 3 gribbles and it won't happen. But when my machine is under tress (my computer doesn't like tempest temple for some reason), it can happen once every 5 minutes. Is probably called about 10-50 times per mob killed. Works 99.9% of the time.

in my macro I have a variable which is always either 0 or 1

    /declare BurnOn                 int         outer       0

I have some code like the following snippet
/call LateEval eval{BurnOn}

sub LateEval(string KissPart)
    /declare Result string 0

    /echo Eval_exp(${KissPart})
    /declare Expression string ${KissPart.Arg[2,:]}
    /declare OrExpression string ${Expression.Replace[OR,||]}
    /echo OrExpression: ${OrExpression}
    /varset Result ${OrExpression.Replace[#,$]}
    /echo Eval_Exp Math.Calc[${Result}]}
    /varset Result ${Math.Calc[${Result}]}
    |/echo Eval_exp(${KissPart}) = ${Result}
/return ${Result}

When the error happens, this is a sample debug output

This is error happening on a druid (one and only character that I've been trying this on) using a modded Kiss. This is the character I'm doing testing on, and not using this on others until I get this resolved.

The fact you are trying to perform math functions on a string variable would be my guess is the cause of your problems.

 

[winnower]

yeah, but that's just the symptom, not the root cause.

I've worked around the symptom.
