Linux: Add a crash handler providing a backtrace for debug builds.
Use case: You're working with a debug version of Qt Creator and you're
interested in getting a backtrace displayed as soon as Qt Creator
crashes without searching for the core file, starting your debugger, ...
Once a 'serious signal' (currently SIGILL, SIGFPE, SIGSEGV, SIGBUS,
SIGPIPE) is delivered, a popup displays the following debug information:
- Qt Creator version (same as in the about dialog)
- Kernel version (uname -a)
- GNU/Linux Distribution (/etc/lsb-release)
- Backtrace (by gdb)
Please note that this crash handler is built and used only in debug mode
on GNU/Linux. It's solely meant as a convenience tool for the developer.
In contrast to the breakpad integration, this crash handler operates
'offline'. There is no network i/o involved.
