 Hello,

 I am using Pyomo and Ipopt on Window 8.1 .
 I experience systematic crashes of Ipopt.exe.
 I checked that from the command prompt using the nl file generated by
 Pyomo


 {{{
 ipopt test.nl
 }}}

 The error screen says:

 {{{
 ipopt has stopped working
 }}}


 I tested:


 {{{
 12 small similar problems with increasing sizes
 4  Ipopt executables, versions 3.7.1, 3.10.1, 3.11.1, 3.12.8
 downloaded from   coin-or.org   or   ampl.com
 }}}


 The success rate varies between 50% (3.7.1)  and 20% (other versions)  .

 The same 12 problems are successful on NEOS.

 I will attach a sample nl file that fails with executables 3.10-3.11-3.12
 .

 Would you have some suggestions that I could try on my own?
 How could I get more info on this problem?

 Thanks for your support,

 Michel
