Packers may strip original sections from PEs and replace them with stubs. In such a case, the exception table still contains references to sections like
.pdata
, even though they are in fact empty.To detect this case, we scan for
.stub
sections. If such a section is present and.pdata
is empty, then we report unwind info as missing. This check is extremely conservative so that it does not cause false positives.
