CONOPT memory limited to 8GB?

[4er4er4er]

There's a complaint in Operations Research StackExchange that CONOPT-for-AMPL does not recognize requests for very large amounts of memory:

According to the user, the "CONOPT space" message says:

• workmeg=100000 gives 0.76 Mbytes
• workmeg=100000000 gives 762.94 Mbytes
• workmeg=10000000000 gives 8191.00 Mbytes

The user might try our conopt4 which should have library-managed memory allocation (it is ASL-managed in conopt 3.17)
