Follow-up Comment #10, bug #54572 (project octave): This looks to be compiler-dependent, as well as compiler option dependent. I have a development version of Octave compiled with gcc version 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.10) and the options '-O2'. This version exhibits the bad behavior. I have another tree where I have compiled the same code with the same compiler, but with the options '-ggdb3 -O0' (for debugging). This version works. This may be a nasty upstream bug where certain optimizations are not being done correctly. _______________________________________________________ Reply to this item at: <http://savannah.gnu.org/bugs/?54572> _______________________________________________ Message sent via Savannah https://savannah.gnu.org/
