Comment:
Well, there was a similar problem in #9357 and I got this answer to the
question of _sig_onm, _sig_off
http://groups.google.com/group/sage-
devel/browse_thread/thread/e8317365bfe9e6e8/2a4148024500dfd2
Note that if the exception is controlled by _sig, it will raise a
RuntimeError instead of ZeroDivisionError. Moreover, with the patch I
provided, all ocurrences of being zero are catched and never reaches the C
functions.
Anyway, I have written a second patch that add the _sig_on, _sig_off to
the problematic functions, so if they have to be added, apply the
following patches (in order):
trac_9345.3.patch
trac-9345-sigs.patch
