annotate libinterp/corefcn/oct-stream.cc @ 22996:36df0e0072a5 stable
distinguish elements vs. bytes in fread (bug #49699)
* oct-stream.cc (get_size (double, ...)): Catch dimension overflow.
Return octave_idx_type instead of int.
(octave_stream::read): Use size_t to count bytes. Use ptrdiff_t to
temporarily count elements, then check against octave_idx_type limits
before copying data to output array.
