This compiler warning is generated if a while loop is based on a condition which is always true.

var
begin   
    while true
    
    endwhile          
end                

In the above example it is clear that execution of the loop will never stop, unless you use a break instruction in the loop, as in the example below.

var 
    bIsFinished
begin   
    while true
        // check something 
        bIsFinished = true
        if bIsFinished
            break
        endif
    endwhile         
end                            

Otherwise this is a very rare warning, but one that should always be addressed.
