I've got an older asterisk running fine:
slug*CLI> show version
Asterisk 1.0.10 built by root at slug on a armv5teb running Linux

So it is possible (at least on my arm variant)!

I had a similar problem to yours untill I stripped the asterisk
config (especially the modules) down to the minimum I need and
then it stopped crashing.
