Unfortunately, both of these examples 19 run fine for me--no errors or exceptions are reported and the PS files are generated OK. I'm running GNAT 4.3. Googling the entire error line above gives 13 results, some from bugzilla for Ada. I don't know how to make sense of of the discussions but I wonder if it was a problem for GNAT 4.1 on x86. I'm open to suggestions on what I can try at this end.

I'll look at these examples again--maybe after I finish off 29 and 30. I recall that some things were being drawn in the wrong colors. One of the examples in the teens (16?) was giving a badly distorted contour plot and I temporarily punted on it, so I'll revisit that as well. > > General example 21 problem for all front ends: > > Example 21 also gives different Ada and C results, but this is a > general > issue with example 21 for all front-ends because of differences in the > external random-number generators being used and in their execution > times. > > We need a volunteer to step forward to change example 21 in C so > that it > uses a simple random number generator that is internal to the example > (perhaps something extremely simple but reasonably effective if you > pick a > "good" seed such as the middle square method described at > http://en.wikipedia.org/wiki/Middle-square_method) and also so that > execution times are not made part of PLplot labels.
