Quentin - Please do rebuilds of octave on FE4 and development due to an upgraded hdf5 library I released. I can do it if you're busy.
OK, done. I didn't realize there was an incompatibility because yum and rpm never complained, until I tried opening octave and saving something in hdf5 format, which resulted in a core dump. Shouldn't the change in API have triggered a new shared library name?
I didn't either until one of our users had problems. Shared library versions is totally in the hands of the developers, and most don't use them properly. Such is life. Thanks!
