<DIV>For the precompiled binaries (3.9.2 in particular), are there any
limitations on the sizes of the arrays?</DIV>
<DIV>I’m working with a problem of packing unequal size circles, which works
fine for up to 20 circles but</DIV>
<DIV>dies for 21 circles. The error message I get implies that one of the
arrays is the wrong size.</DIV>
<DIV>I’m using Mathematica to calculate the objective function, constraints, and
the various derivatives.</DIV>
<DIV>The problem could also be in my interface to Mathematica.</DIV>
