<DIV>Well OSX is certainly a better platform for development work than Windows
thanks to projects like homebrew. Though Apple has a habit of breaking
everything every 6 months. Linux version upgrades are usually a bit smoother,
but that’s because distributions have buildbots that recompile the world in a
compatible way.</DIV>
<DIV> </DIV>
<DIV>Looking over the tickets list again, there was a report that Ipopt 3.10.x
might not have this problem. Ipopt 3.10 doesn’t have the code to use Matlab’s
version of MA57, and I’m a little surprised since I don’t remember 3.10 and 3.11
being all that different, but it could be worth looking into. If you can
identify the newest version that consistently works and the oldest version that
consistently crashes, then maybe it was some change in the code or in BuildTools
that seems to be causing problems more often on newer versions of OSX.</DIV>
<DIV> </DIV>
<DIV>Looking at the history, I did make a few changes in the Matlab interface
around that time - removed auxdata since it leaked memory, made the intermediate
callback more capable, and a bunch of fixes in the build system. If it’s
possible to bisect the problem down to a single commit, then maybe this is
fixable.</DIV>

<DIV>I am surprised that Windows is the most stable platform for using Ipopt
with MATLAB. I switched to a Mac for stability and I am finding that it might
not have been the best decision in the long run. </DIV>
