I also tested it such that all the variable declarations at the top had their own new line (which I didn’t think would make a difference) and it didn’t make a difference.

You say this is a compiler optimization issue not a player issue… I am testing this in the latest Flash Builder Plugin for Eclipse on a PC (build 272416 targeting the 4.1.0.16076 SDK)

[CODE]
var a:int = 7, b:int = 31, c:int, i:int, m:int = 1000000;
var t:uint = getTimer();

while ( i < m )
{
c = a + a + b;
i++;
}
trace( "complex", getTimer() – t );
i = 0;
t = getTimer();

while ( i < m )
{
c = a + a;
c += b;
i++;
}
trace( "multiline", getTimer() – t );
[CODE]

I’m getting zero length files with the linux standalone 10,1,53,64 players

Have you had any luck tracing into flashlogs.txt with *any* 10.1 players?

Nevermind, I can’t comprehend basic English.
