Stack-Heap collision in a low count list?

ok I think I've got this traced to the folowing function

fWarpPos( vector vPosGoto ){
    vector vPosCurrent = llGetPos();
    list vLstBase;

    llLookAt( vPosGoto, 10.0, 1.0 );
    llSleep( 1.0 );

    while (llVecDist( vPosCurrent, vPosGoto) > 10){
        vLstBase += [PRIM_POSITION, (vPosCurrent = llGetPos() + <0, 0, 10.0> * llGetRot())];
    }
    vLstBase += [PRIM_POSITION, vPosGoto];

    llStopLookAt();
    llSetPrimitiveParams( vLstBase );
}

when I first got the error the object (a default .5m diameter sphere, non physical) was ~60m east of the target coordinates, any thoughts?

Admittedly, I'm still learning the quirks of LSL myself.

Have you tried changing

list vListBase;

to

list vListBase = [];

Or it's likely your "while" is filling the list past the memory.


while (llVecDist( vPosCurrent, vPosGoto) > 10)
{
vListBase += [PRIM_POSITION, (vPosCurrent = llGetPos() + <0, 0, 10.0> * llGetRot())];
}

gah, nevermind... I was repeatedly calling from llGetPos, so it never advanced past the first 10m call... just kept looping the first move

corrected to

fWarpPos( vector vPosGoto ){
    vector vPosCurrent = llGetPos();
    list vLstBase;

    llLookAt( vPosGoto, 10.0, 1.0 );
    llSleep( 1.0 );

    while (llVecDist( vPosCurrent, vPosGoto) > 10){
        vLstBase += [PRIM_POSITION, (vPosCurrent += <0, 0, 10.0> * llGetRot())];
    }
    vLstBase += [PRIM_POSITION, vPosGoto];

    llStopLookAt();
    llSetPrimitiveParams( vLstBase );
}
