[Insight-developers] StimulateImageIOTest: Strange Test Failures

[Bill Lorensen]

Luis,

The print did it. It turns out that the code was using sscanf to parse
the data file name. If the data file name had an internal space, the
sscanf stopped there. I replaced the parsing code with a regular
expression that removes leading and trailing spaces. I'm not sure why
the input code did not detect a bad filename.

Checked in the changes. Also, yesterday I found the problem with the
VTK IO test that was failing. I think that leaves us with one failing
gdcm related test on SUN OS.
