Description
|
A licensee (see comments for details) has isolated a bug in the null-check
eliminator. Since exception handlers are not traversed during the dataflow
walk, incorrect not-null results can be created for values which are assigned
null values inside of exception handlers. This may cause a VM crash if such
compiled code is ever executed and if the receiver is dereferenced at a point
where the compiler assumed the receiver was non-null. A patch has been
submitted.
