5505: FP: Array accessed out of bounds
2014-03-09 08:47:18 +01:00
Heinrich Schuchardt bd67db96f1 5505: FP: Array accessed out of bounds
CheckBufferOverrun::checkFunctionParameter alreacy considered usage of a
function parameter inside an if block as a special case.

With the patch the same is done for switch statements.

A test is added.
