[Octave-bug-tracker] [bug #56149] An HDF5 file which fails to load causes segfault when eventually exiting

[John W. Eaton]

Follow-up Comment #4, bug #56149 (project octave):

Here is what I see:


octave:1> load example.h5
error: load: error while reading hdf5 item all_measurements
octave:1> quit

Thread 1 "octave-cli" received signal SIGSEGV, Segmentation fault.

Since the segfault happens inside an HDF5 library function, maybe we are
failing to clean up properly after the error?  H5close is not closing a file,
but is intended to free resources used by the HDF5 library.
