Nonlinear solver prints random strings instead of system names

[Martin Sjölund]

Nonlinear solver prints random strings instead of system names, for example the following:

[martin@mega msl32]$ for f in `seq 1 100`; do ./Modelica.Electrical.Machines.Examples.SynchronousInductionMachines.SMEE_LoadDump |& grep -o "Error.*time" | uniq; done

Running the executable through gdb always gives the same string (Error solving nonlinear system �K�). So something is fishy.
