Research direction

No source file or test is named. Reproduce the issue by opening the supplied "zinc rush flows totally" x86 executable in Binary Ninja 5.1.8005-dev on Windows, then trace the analysis path responsible for the repeated 0x3e8 integer-size warning; done means the file opens without that warning.
