[Ipopt] Memory error

[Rishi Amrit]

Hi,

   I'm using the mex interace from MATLAB to call IPOPT. One of my IPOPT
calls crashes MATLAB and returns for following backtrace:

This error was detected while a MEX-file was running. If the MEX-file
is not an official MathWorks function, please examine its source code
for errors. Please consult the External Interfaces Guide for information
on debugging MEX-files.
