Details:

Hi

the function doesn't seem to like integers and segfaults when presented with
them:


octave:1> a = int8 (randi (255, 10, 10));
octave:2> dot (a, a)
panic: Segmentation fault -- stopping myself...
attempting to save variables to `octave-core'...
save to `octave-core' complete
Segmentation fault


I can reproduce this with uint and int8/16/32/64. Also, it's enough for one of
the entries to be of the integer classes, the following also segfaults:


octave:1> a = int8 (randi (255, 10, 10));
octave:2> dot (double (a), a)
panic: Segmentation fault -- stopping myself...
attempting to save variables to `octave-core'...
save to `octave-core' complete
Segmentation fault
