Dear crash-utility list,
I played a bit with snap on RHEL 4 and besides the fact it doesn't build out of
the box (trivial Makefile compatibility problem), it seems it doesn't really
dump a full core properly (at least on the system I tested).
Since this is not really something that is supposed to be supported I am posting
this here rather than opening a Bugzilla. I haven't attempted to repro on other
distros.

Is that expected? Any idea what's going on?
Thanks,
