Run a program transparently, but print a stack trace if it fails

For automated unit tests I wanted my program to run normally, but if it crashed, to add a stack trace to the output log. I came up with this command so I wouldn't have to mess around with core files.

The one downside is that it does smoosh your program's stderr and stdout together.

Alternatives

There are 4 alternatives - vote for the best!

gdb --batch --quiet -ex "thread apply all bt full" -ex "quit" ${exe} ${corefile}

This does almost the same thing as the original, but it runs the full backtrace for _all_ the threads, which is pretty important when reporting a crash for a multithreaded software, since more often than not, the signal handler is executed in a different thread than the crash happened.

The pstack command prints a stack trace of running processes without needing to attach a debugger, but what about core files? The answer, of course, is to use this command. Usage: gdbbt program corefile
