I doubt this limitation is practical. Will all know that the compilers
are buggy and that the number of compiler mistakes increase with the
optimization level. The increase is not gradual, however. IMO, either
a decent-size program will work with -O3 or it will not; and if it
will not work, there will be lots of reasons why it won't, not just
mixing local variables with pointers to those local variables.

And, at any rate, the Squid code in question does not really mix
anything.
