Comment (by FabiF1):

 Hi DK,

 If you're using Matlab, I would expect you to have written a mex-file.
 If that is true, wouldn't it be possible to implement a "Try-Catch" that
 would surround the call to ipopt, and if any error "known" or "unknown" is
 caught, then exit properly the mex-file with a:

 {{{
 try{
 }
 catch(...){
 mexprintf('Oupsss... Ipopt mexfile exits!')
 }
 }}}


 You can also improve it by catching specific error and react differently.

 Nonetheless this should enable you not to take down Matlab when a C++
 exception is thrown.

 Cheers,
 Fab
