Problem with /fox3 when /fox2 is also enabled

[cpyrgas]

Came across a problem with /fox3, which seems to surface only when /fox2 is also enabled. When /fox2 is disabled, following code works fine. When /fox2 is enabled, it throws a runtime error "Variable does not exist: TESTEXPORT"

#pragma options("fox2", enable)

#pragma options("fox3", enable)
#pragma options("allowdot", enable)
#pragma options("lb", enable)
#pragma options("memvar", enable)
#pragma options("undeclared", enable)

CLASS SeparateClass
	PROPERTY OtherProp AS INT AUTO
END CLASS

CLASS MainClass
	EXPORT TestExport := SeparateClass{} AS SeparateClass
	
	METHOD DoTest() AS VOID
		TestExport.OtherProp := 456
		? TestExport.OtherProp
END CLASS

FUNCTION Start( ) AS VOID
	MainClass{}:DoTest()
