The included crashreport.gdb allows for semiautomated hunting of
crashes. The crashlog-file will be named backtrace.log and contains all
the commands required to partially automate a crashlog-creation with the
proper information.
Usage: gdb -x crashreport.gdb <executable file>
For creating an efficient backtrace, use -DCMAKE_BUILD_TYPE=Debug as a
parameter to CMake during configuration - this increases the filesize,
but includes all the needed information for a decent and efficient
crashreport.
-- Good luck, and happy crashhunting.
