Here is an example where a global solver fails. This is actually a run on NEOS. That something goes wrong we have to accept: that can happen. However the feedback is rather poor. As a modeler I have no clue what to do now.
I think that software should be be built in a much more defensive style. Good feedback especially when something is going wrong is underappreciated by many developers.
Note: this may be a NEOS related problem, I don’t know at this stage.
Update: there seems to be a bug involved. Just for a fraction of second or so I saw a message:
Error: *** glibc detected *** /opt/gams/latest/gmsgenux.out: double free or corruption (out): 0x0000000009286c20 ***
It is noted that this is not the latest GAMS version, which is 23.9.
