I actually did it once we talked (may be I missed something).

Once the program is compiled with -fomit-frame-pointer you do not get stack
trace at all, and this is default at optimization levels -O1 and above
starting from gcc-4.6

So once I changed it actually worked - got stack trace (with gcc-4.2) 

but once gcc is upgraded it would be usless and I assume it may also be
dangerous.


If you want I can send you a patch (I prepared it as I seen that
many programs actually use libexecinfo) but I don't think I
want it in the mainstream.
