On Linux and most other operating systems I know of, passing a NULL to
a %s format specifier is safe. On Solaris, as it turns out, it isn't
[1].
The case in the filed bug is fairly trivial to fix, but I'm wondering
if this is something that should be added to the Code Style /
Portability section of README.developer?
Alternatively, since I have no idea how many of these bugs we may have
to fix, perhaps we should be wrapping all format strings somehow?
Hopefully someone with some Solaris experience (or even a Solaris test
box) could weigh in, since I have neither.
Cheers,
Evan
