[Ipopt] More Mac Mex File Crashes

I have reported this problem before, but I am reporting it again because it
seems as if it has not been fixed.  I continually get crashes when I run
the Mac OS-X versions of the precompiled IPOPT mex files.  I do not know
why the crash occurs, but it happens frequently and it seems as if it is
specific to the Mac.  An example of the crash is shown the following crash
dump file.

To be honest, I have no idea why such a problem exists on a Mac (which is
UNIX, so I would expect better reliability).  This problem does not seem to
occur on a Windows machine (makes me want to switch to Windows, perish the
thought!).  Anyway, any help is greatly appreciated.

On a separate note, are there IPOPT mex files (or equivalent) for languages
such as Python, R, or Julia?  If so, has anyone uploaded precompiled
versions of such executables for these other languages?  Finally, would any
such mex files have MA57 capability, or would they be limited to just being
able to use Mumps?

Thanks in advance for any help anyone can provide.
