本页面介绍了类似的堆栈溢出问题。这似乎增加了跟踪某处功能将修复它。

这是一个已知的bug

function testFunc(val1:int, val2:int, val3:int):int {
    var returnVal:int = 0;
    return returnVal;
}

var val:int = testFunc(1, 2, 3);

causes

locals: Main int int int * 
4:dup VerifyError: Error #1023: Stack overflow occurred.

This page discusses a similar stack overflow issue. It seems adding a trace somewhere in the function will fix it.

It's a known bug
