i usually do a
export CFLAGS=-O3 -march=pentium3
export CFLAGS=-O3 -march=pentium3
before configuring and compiling a package. This way you don't have to
alter the configure scripts manually.

The crash is not limited to special packet types. Also it does not crash
while _capturing_ but it crashes when it comes to displaying the captured
packages.
So i can capture a whole stream (without real-time screen updates). And
when i then stop capturing ethereal crashes. the same happens when loading
and displaying a saved packet dump (it then crashes immediately without
really capturing any packet on the wire).

I doubt that this is really a ethereal bug, my mail was more intended to
be a "heads up".
