should divide-by-zero generate a SIGFPE?

[Paul Goyette <paul%whooppee.com@localhost>]

As some of you have noticed, I've been slowly migrating some of the old 
src/regress tests to the new atf format.  I've discovered that the test 
for SIGFPE in src/regress/lib/libc/siginifo/sigfpe/ doesn't work.  It 
attempts trigger a signal by

        {
                double d = strtod("0", NULL);
                ...
                sigaction(SIGFPE, &sa, NULL);
                printf("%g\n", 1 / d);
                ...

But the routine specified in sa.sa_sigaction does not get called, and 
the test fails.

So, is this expected behavior?  I did a quick bug search and didn't find 
anything relevant.

If this is expected, is there some other way to reliably generate a 
SIGFPE?


BTW, if it matters, I'm doing this on port-amd64.
