How to get c++ abort to generate backtrace

[Orion Poplawski]

We're seeing cmake crash on the ppc64 builders with the following:

terminate called after throwing an instance of 'std::out_of_range'
   what():  basic_string::erase

Is there anyway to get this to automatically generate a stack trace? 
When I try running the process under gdb I don't get the crash so I've 
been unable to debug that way.
