Testing Suite Bug with Semantic Expressions

[CanBerker]

The following test annotation fails with the assertion given below:
(:JIQS: ShouldCrash; ErrorCode="XPST0008"; ErrorMetadata="LINE:3:COLUMN:6:" :)
for $i in ()
where $j eq $i + 1
return $i

java.lang.AssertionError: Program did not compile when expected to.
Error output: Error [err: XPST0008]LINE:3:COLUMN:6:Uninitialized variable reference: j

It appears that this test case causes a semantic exception which later hits a shouldCompile() check that always returns true, effectively causing the given exception. If semantic exceptions are a part of test cases handled at runtime, a fix may be needed here.
