iirc, drouting accepts only digit based prefixes. Alphanumeric keys are 
not suitable for tree structures, like used by drouting, because there 
will be soo many children for each node that will use lot of memory.

Anyhow, it should not crash, do you have a backtrace or a log for it?

Maybe you can combine several modules to get you go, if you want to use 
drouting. Like using mtree (it has a way to define the characters 
allowed in the prefixes -- still not suitable for all the characters) or 
htable to map your alphanumeric key to a digit only key. Then you can 
use the result with drouting.


Cheers,
Daniel
