No source file or test is identified. Start by reproducing the report on win32 with Kaspersky using version 2.1.263, then compare the supplied feedback ID and VirtualMessageList stack trace to determine whether the antivirus detection and runtime error are related. Done means the false-positive cause is confirmed and a verified resolution is available.
