[Ipopt] Termination code 11

[Johan Åkesson]

Hi,

I tried with a fresh 3.6.1 - here are my findings:

 - If I configure with --enable-debug the model solves as expected, that 
is, no termination code 11.
 - If I configure without --enable-debug I still get termination code 11.
 - If I run valgrind, I get the following printout:

I do not know what la_replace is - is it part of IPOPT? Please let me 
know if you would like me to submit a bug report.
