Problem description: 

I have a very simple that references a static variable, has worked for over a year in all previous versions. Now, attempting to access the static variable generate "Internal error $(ARG1)"

Steps to reproduce:

Here's a trivial reduction of the bug.  Run the following:

Sub bug
	static myVar as Integer
	if myVar = 0 then
		msgbox("first time")
		myVar = 1
	end if
End Sub

Current behavior:

Internal error $(ARG1) upon the test "if myVar = 0"
Same result if you try to assign to myVar instead of query it - any attempt to reference a static variable fails

Expected behavior:

myVar is found equal to 0 first time the sub is run.
