Global test environment tear-down segfaults after adding Abstract Test Pattern

[Katy Huff]

Hi All,

I'm trying to implement an Abstract Test pattern for testing an interface (FacilityModel)  in my code (Cyclus).

I have followed the instructions at code.google.com/p/googletest/wiki/AdvancedGuide#Creating_Value-Parameterized_Abstract_Tests and have succeeded in running the FacilityModel abstract tests for my SourceFacility. Hooray! The instructions were very helpful and straightforward. Thank you! 

Unfortunately, the global test environment tear-down step is now failing with a segfault.

Can you tell if there there is a destructor or TearDown() method that I'm missing?

I'll very much appreciate your help.

All of my source code is at  cyclus.googlecode.com . Files pertinent to this change were committed in revision 566 (http://code.google.com/p/cyclus/source/detail?r=566). It is worth noting that in my code, gtest is implemented in conjunction with ctest (part of cmake) via a single header file. I'm a fan so far, though I haven't implemented many tests, as you can also see in the repository. There's a project I modeled this after (ITK). Here's a discussion which describes the use of their googletest framework and compares it with boost tests http://www.itk.org/Wiki/Proposals:Increasing_ITK_Code_Coverage .

Anyway, the troublesome gdb output follows:

Thanks for giving it a look,

Hi all, 

After slogging through plenty of valgrind, I found my problem. Not unsurprisingly, it was related to incomplete object initialization in my setup functions. 

So, please disregard my previous request for help!

Thanks,

Katy
