[Insight-developers] My first bug fix (10770)

[Bradley Lowekamp]

Hello,

I committed a patch to get things building again.

You can observe the problem under linux if you run it under valgrind as well.  I think it relates to allocation of some zero length c strings in the test.  This is occurring in a clean checkout.

I do hope that you are not including the testing as part of the "administration" costs. Testing and validations are very important things, as much of the time if it is not tested it will not be working ( or at the least it will break and no one would know ).

I made an experimental build http://www.cdash.org/CDash/buildSummary.php?buildid=629158 (release 3.18.0 with my changes), and the are 2 tests failing (they don't seem to be related to my changes though). Is that a problem?
