[fpc-pascal] Unhandled Exception

[Steve Gatenby]

I have an intermittant exception in my Lazarus app (Access violation)
My app also uses a freepascal library - I think the problem is within it

Can anybody suggest the best way to narrow this down to a unit / 
function / line ?
I believe I have the Frame stack captured, but have no idea what to do 
with it

I have read the wiki on logging exceptions, but this seems to only give 
me address info, and I cant figure how to translate this to something useful

Thanks - SteveG
