Summary0000544: IPOPT fails with models/test/ipopt/test2.a4c
DescriptionThis model has only an objective function, no additional constraints. Perhaps IPOPT can not handle this case, or perhaps we have an error in our implementation.

Tested with IPOPT 3.10.1 (Ubuntu 12.04 package) and ASCEND at trunk changeset 4070.

The problem DOES NOT exist with IPOPT 3.10.0 (self-built) on Ubuntu 11.10.
TagsNo tags attached.

Note that IPOPT on Ubuntu 12.04 works fine with the other test cases: tests 5-14 are all OK.
