Thank you, Bill.  I don't know.

I have since learned that the crash only occurs if I leave my old build directory (the product of CMake 2.8.7 on Mac OS X 10.7) in place.  If I remove the old build directory before invoking CMake 2.8.8, then CMake 2.8.8 does not crash, although unfortunately there are other issues :(

The thing I am building is an NPAPI Plugin based on Firebreath.  Firebreath is open source, and although the code I add is not open source, I can publish it freely.

Usually when I try to build an open source project it takes me a long time to get it working, and I'm not always successful.  I'd rather not.

Although I have already worked around the problem by removing my old build directory, if Kitware wants to pursue this further, I shall try to zip up all needed files and send to you with instructions how to reproduce.  Before doing that, if someone would send me a Mac OS X binary of the latest RC, built with symbols unstripped if desired, I'll use that.  I presume that the CMake.app application is just a little GUI wrapper around use/bin/cmake, and that I only need the 'cmake' binary?

All that being said, you also realize that the crash report I posted earlier can by symbolized using gdb if someone archived the .dSYM file before shipping :)
