Summary: info about compiler bugs

The compilers released by Apollo with sr9.5.1 have some significant problems
in the code optimizer.  You may or may not hit them, but if you do all sorts
of strange things can happen.  The sr9.6 compilers are much better.

About problems with malloc: remember that before 9.5 the Apollo memory allocation
paradigm did not mesh well with what Unix-like programs expect (reference the
"set sbrk size" kludge, among others).  In 9.5 and later systems to match what
a Unix-like program would expect; but I wouldn't be surprised if programs that
intimately knew about the old system wouldn't run on 9.5 and later systems.
