You are looking in the wrong direction. Some of the regression tests
actually produce errors, and the regression test runs the same test, and is
supposed to produce the same errors.
In this test, 34.5 is not a valid integer. 100000 is an integer, but
outside the 2-byte range (which goes -32768 to 32767). And 'asdf' is simply
not a number. So, all these error messages are good and right.
In a regression test, always look at the *diff* files. They tell you what
the differences were between the original and your test, whether the
original result was a normal one or a deliberate error.
My guess is that in your case, you will simply find that the difference
results from some different error message. Perhaps your system would say
"out of range" instead of "Math result not representable". Check the diff.
If this is true, then you have nothing to worry about.
