If a Tex file inputs a missing file the builder errors out and the message is totally obscure. There is a logic flaw that results in a an uninitialized reference that needs to be fixed so we get the LaTeX error message instead of a failure in the builder.

I put a patch for this issue in https://bitbucket.org/managan/scons_newglossary-fix
The test is not working yet. I need to figure out how to run a test and distinguish a bad stderr result from a "good" stderr result.

Fix typo in summary
Found the original email that prompted this so I think I should be able to find it or reproduce it
I have reproduced this. Could not find the original patch. Need to work on a test.
I reproduced the bug and the fix. No test deck yet. What is the link to the current development process of submitting a branch...
Thanks, still at the point of trying to figure out how to distinguish if SCons fails with an exception or just by failing to produce output. The user request was to avoid the exception and have SCons tell you what went wrong.
Are there tests that look for a specific type of failure? Or do you have to write a wrapper to latex like some do and just test the scanning failure...
For clarity I am at this point. The stdout and stderr are expected but cause test.run to fail.
