This has nothing specifically to do with the 8051 - so should really be in Chat...
I apologize. There was an earlier chain on the subject. That is why I posted here. Andy Neil said:
Usually not.
Usually this means that the code is faulty, and only works by luck in the unoptimised version; eg, it may be based on some false assumption that just happens not to fail when unoptimised Yes, if the persons coding, and reviewing, are not familiar with dark corners of the language specification, that can happen.

NB: in the case of an open-source compiler, who do you consider to be the "vencor"...? For the GCC there is http://gcc.gnu.org/bugzilla/. Of course, since it is open source, one can have a shot at fixing it. |
