make check hangs at chol.cc

[kahacjde]

Hello all,
with the current tip make check hangs at chol.cc. WhenI interrupt it
with ctrl+C I see the message:
"chol: unexpected second or third input". The fntest.log does not
contain any useful information about the reason. Any ideas?

I don't see this problem.

To debug it on your system, I suggest you try extracting the test code
from chol.cc and running it directly in Octave under gdb.  Then when
it hangs, you can interrupt Octave to see where it is stuck.  If it is
in an infinite loop, you may have to step or continue and stop
multiple times to see where the loop is happening.

O.k. I could isolate the problem a bit. After running the inv command octave hangs.
