OK, before I start hacking, what is it that you need once I have found a
function?

What I can do is try to identify a function or minimal functions that, when
compiled in a file with optimisation, will cause Emacs to detect inconsistent
internal state, but not when compiled without optimisation.  I can compile this
file with "-g -O0 -fno-unit-at-a-time",  "-g -O1 -fno-unit-at-a-time" and "-g
-O2 -fno-unit-at-a-time".  I can compile all other files with "-g -O2
-fno-unit-at-a-time".  Does this sound right?

Once I've found it, what would be useful to you?  Output from -E for that file?
 Files generated by -S for that file using the flags above?  Some other
internal gcc output?

Assuming that I am able to debug this function, any pointers as to what I could
look for that might explain why it is functionally different when compiled with
optimisation?
