[Insight-users] Bug in itkMultiThreaderPThreads.cxx

[Fleysher, Lazar]

Hello Matt

yes, there were two places where the error-code was not checked. In the third one it was.
With the patch, at least a meaningful error message will be generated without a segmentation violation.

Thank you very much for your help

Lazar
