[Octave-bug-tracker] [bug #58268] hdf5 load crashes on strings

[Elvis Stansvik]

Follow-up Comment #4, bug #58268 (project octave):

Thanks for the fix Rik! However, I tried the test case out, using Octave from
hg and with debugging symbols, and I still get a crash, though with the
following backtrace:
