No, for me my bug is worse than #2820: I do not see any stack 
trace. I do not claim that there is a bug in a compiler (actually 
I am almost sure that it is my mistake and I do something like 
freeing memory twice).

I need help to get a stack trace for the very reason that I do 
not want to spend time producing a minimal example, but want to 
use a debugger instead.
