Details:

Jeremy tried the gtk3 build on osx and some tests failed. All failing tests
use the histogram graphical output. I build on osx from git with macports and
see the same problem. For me the tests:

   Subject: [GNU PSPP 0.8.4] testsuite: 497 1019 1022 failed

failed. When I run test 497 manually several times I see the following:

So there are some strange characters appended. And the pattern changes. Maybe
this bug is related to bug #43469 which was due to implementation of cairo on
osx. The current macports has cairo 1.14.2 which includes a patch for the text
rendering on osx.

When I open the the sps file from test 1019 and reduce it to:

========

input program.
loop #i = 1 to 1000.
 compute x  = rv.normal (56, 3) + rv.uniform (1, 1).
 compute y  = rv.normal (6, 2) + rv.uniform (1, 2).
 compute A  = rv.uniform (-1, 1).
  compute A = (A > 0).
 end case.
end loop.
end file.
end input program.

examine x y
        /plot = histogram.
===================

then I see the screen as shown in the attachment. The strange characters
change when I resize the window. So I guess there is some memory issue here.
