[Octave-bug-tracker] [bug #55347] PVS studio static analysis report

[Rik]

Follow-up Comment #41, bug #55347 (project octave):

The static analyzer, perhaps legitamately, gets very suspicious of
dynamic_casts.

Do we want to fix this?  I don't really know.  idx-vector is pretty
fundamental and I'm not sure we want to introduce even a small delay in to one
of the tightest inner loops of Octave.  It also seems likely that if we were
getting this wrong at a structural level then we would have lots and lots of
bug reports.  So as long as the input pointer before any dynamic_cast is valid
I think it is an exceedingly rare event that it can't perform the dynamic_cast
at runtime.
