[Octave-bug-tracker] [bug #54405] octave_idx_type index integer overflow math check doesn't work correctly

[Rik]

Update of bug #54405 (project octave):

                  Status:                    None => Ready For Test

Follow-up Comment #10:

I think it is worthwhile to put the check for overflow within the get_size
routine so that anyone that calls it (fread, sscanf) can get the benefit
rather than just fread.  Also, there is no need to call return after a call to
the execption-based error function.  See this cset
https://hg.savannah.gnu.org/hgweb/octave/rev/39fd627b2c5d.

It might be nice to have some BIST tests in io.tst for these exception
conditions like using Inf, NaN, or large index sizes.

Marking as "Ready for Test".
