Details:

One of the "make check" tests for onenormest crashes.  Reproduce with
   N = 100;
   A = rand (N);
   [nm1, v1, w1] = onenormest (A);
my result is
panic: Illegal instruction -- stopping myself...
attempting to save variables to `octave-core'...
save to `octave-core' complete
Illegal instruction

This is a fresh octave 3.4.0 build on Debian stable (squeeze) amd64.  I have
all autoconf-detectable libraries turned on except HDF5.

I can isolate the crash to the
   Y = feval (apply, X);
statement at line 154 of onenormest.m.
