I don't understand why you say there is a miscompilation.  The blog
describes it as: from the "s->x" the compiler infers that s is non-null,
so it optimizes away the test.  But it's equally valid to say: the
compiler optimizes nothing; the null dereference is executed and since
the action is undefined, the machine can do whatever it likes, such as
jump around the comparison against NULL.

Who says undefined behavior has to mean "crash"?  It can mean "generate
a crossword puzzle", it can mean "erase the hard disk", it can mean
"ignore the next comparison and keep going" (equivalent to optimizing
the comparison away), etc.  The point is that the execution path is no
longer under the programmer's control.  So I wouldn't say the compiler
miscompiled anything: the compiler is only responsible for programs that
don't engage in undefined behavior.

I think by this you mean that the undefined behavior should be
consistent across compiler settings, but "undefined" explicitly means
you can't expect consistency.  One possible conclusion (given the
observed difficulty of even expert programmers to avoid these bugs) is
that using C for anything critical is crazy.  The Ada guys have been
saying that for 30 years, maybe with good reason.  If it helps, though,
 
   http://blog.regehr.org/archives/213

(same guy, and he has tons more examples and analysis of similar issues)
discusses the case for C acting the way it does.

It might be interesting to build that into the compiler if that doesn't
slow down compilation too much.  Other fancier checks are more expensive
though.  http://stanford.edu/~engler/ has lots of good links.

Well, the undefined behavior is part of the language design, so the
standards committee is a better target of that criticism than the
compiler writers.  And C programmers routinely overestimate their
ability to avoid undefined behaviors in their code.  The other part, as
you say, comes from the very high complexity of today's software.
Static analysis appears to help even for Java, which has very little
undefined behavior.  And Ada was designed to be friendly to static
analysis.  I've never used it but may get to try it on something soon.

Hardware guys have their own attitude problems, of course: they will
screw up the useability of a design in order to save 2 cents worth of
transistors.  For example, comp.arch.embedded had a huge thread not that
long ago, about floating point microcontrollers that implement IEEE 754
arithmetic slightly incorrectly in order to simplify the circuitry, that
breaks some numerical algorithms in subtle ways.
