Re: Coding system of file not recognised correctly

[Richard Stallman]

    But it's there again in my own, self compiled Carbon Emacs 22.0.50,  
    that uses the same sources (except some minor C code differences) as  
    the X client one. And the same compiler switches ? it could be just a  
    question of optimisation flags!

That is a rare occurrence but it is not impossible.  It can happen
that C code's meaning changes depending on optimizations, and compiler
bugs can also happen.

To track down such a bug requires the same methods as tracking down an
ordinary bug: you have to localize the code that works wrong when
compiled a certain way.
