[SR-Users] Segment fault

Hello,
in a quick look at the trace and the code, the assignment with empty
value seems to be the issue, likely to be:
$rU = $dbr(ra=>[0,1]);
I remember that a similar issue was fixed long time ago, but not sure
before your version (3.2.x) which is very old right now. If you have
time, you can simulate the same situation using a more recent version
such as 4.2 or 4.3.
Being traveling, I can't do much testing and analysis of the commit logs
to see what and when was fixed.
For the moment, you can try to catch the situation in the config:
if($dbr(ra=>[0,1])!="") $rU = $dbr(ra=>[0,1]);
Cheers,
Daniel
