</div>By "enabling debug settings in make.conf", I do:<br>
Add "-ggdb" to "CFLAGS"<br>
and add "splitdebug" to "FEATURES"<br>

So I guess, the "debug"-useflag is not necessary for<br>
backtrace. But as you say: I guess, it won't harm either. ;)<br>
<br>
On the other hand:<br>
There is a general rule: Changing compile options will<br>
change the binary produced. So an error being present with<br>
normal compile options, _might_ disappear with debug settings.<br>
<br>
