And GNU libc checks strings passed to printf for a %s placeholder for NULL, when the C standard says this is not allowed. So a lot of code that runs fine on Linux would blow up on Solaris. I think eventually the Sun engineers relented and held their nose and made Solaris libc similarly check.
So I don't think anyone has full claim to being pure as the snow...

They did, and your statement is true enough (though, as usual, general logging functions still have to guard against unintended NULLs, because where you can get unintended NULLs you can also get wild pointers, and those will crash anything). But as a general principle, glibc is more paranoid than Solaris libc. (Everyone at work moans about this except for me. I celebrate it. It's caught a good few bugs, although less than the saviour of all tricky bugs, valgrind :) )
