When Sage starts on my OpenSolaris machine it crashes, with a segfault and a
message about "...or is not properly wrapped with _sig_on, _sig_off"
Having a look in the source code, I believe _sig_on and _sig_off should be in
pairs - is that correct? If so, should there not be an equal number of _sig_on's
and _sig_off's in any one file?
A quick check shows this is not the case - see below. One file in particular
(sage/libs/pari/gen.pyx) has 332 occurances of the text _sig_on, but only 33
occurrences of _sig_off.
My checking ignores comments, but a quick check of at least a few of the files
below shows that the differences are not due to comments (but in some cases it
might be, there are some lines with a comment which contain _sig_on or _sig_off).
In the list below, the filename is followed by the number of lines with _sig_on
or _sig_off. The first is the _sig_on and the second the _sig_off.
Does this indicate a problem, or am I worrying about nothing?
