I'm quite sure I'm talking about that very same compiler when I say: no, 
those weren't bugs.  They were the amply documented effect of that 
compiler being run in an explicitly _not_ standard compliant setting.

No.  It was running in a "let's not even pretend this micro is actually 
big enough to efficiently implement C without seriously breaking a large 
fraction of the rules" mode.

Many, maybe all the C compilers for small 8-bitters have such a mode, 
and often that's their default mode because, frankly, the 
standard-conforming mode would be nearly useless for most serious work. 
OTOH, those micros, and the projects they're used in, are generally 
small enough that you don't really have to go all MISRA on them.
