Jacob,
I just went and looked at the code for the symbol_record class and it looks
like the copy constructor only increased a reference counter. It actually
doesn't do a deep copy as you expected. I noticed this because I went back to
check why rand(10000,10000) in Quint wasn't using 2 times as much memory as the
same command in just Octave. I think this implies that despite the best
intentions of OctaveLink, carrying around a reference to variables still being
manipulated by the Octave internals destroy and thread-safetiness that
OctaveLink is intended to provide, as you could access these references outside
the Readline idle event loop.
I don't know if it is a related problem (I expect it is), but if you try to
clear the large random matrix, Quint crashes.
Try:
zz = rand(10000,10000);
clear zz
This crashes every time on both Ubuntu and OSX when updating the
VariablesDockWidget. It doesn't happen for certain smaller variables, but I'm
not sure why.
