nsIDOMCSSStyleDeclaration::GetPropertyValue () Please help, seems to be leaking?

[Niky Williams]

I've created my own Marquee type effect...the <MARQUEE> tag just wasn't 
robust enough.  Here is my problem.  I use 
nsIDOMViewCSS::GetComputedStyle () to get a reference to 
nsIDOMCSSStyleDeclaration, works find and dandy, then I use 
nsIDOMCSSStyleDeclaration::GetPropertyValue () to get various 
properties...left, top, width, height are the ones I'm using.  Here is 
where the weird part comes in.  I have a timer, fires off every 20 ms or 
so to make this marquee/scroller work.  Looks good on the perfmon for 
about 1:45...after that the mem allocation of my program starts to rise 
out of control.  If I comment OUT the 
nsIDOMCSSStyleDeclaration::GetPropertyValue () (this is the only change 
I make) mem allocation stays stable...flat line on the perfmon where it 
should be. I realize by doing it this way in a timer thread, and not 
within the actual Gecko event loop, that it's probably not exactly 
thread safe...but I don't believe it would be causing this issue  Is 
there a possible leak with nsIDOMCSSStyleDeclaration::GetPropertyValue 
() or does anyone know of any issues with this function? Please help, 
I've been working on this all morning trying to figure it out...very 
frustrating.
