>> what is the reason for this not being the default behavior? 
Some of it are historical reasons (e.g. valgrind does that).
Some of it is performance considerations: _exit(1) is faster than abort() 
in some of the performance-critical settings. 

>> I just got a completely different stack trace when enabling this.

Hm? That's weird (unless there is a race in the code which 
just makes the reports different from run to run)

I am closing the bug now since the functionality is in place.
We will probably not change the defaults.
