something like that (or for example extending checking the non-null attribute to more than rejecting NULL-constants but also variables that are always NULL) and you need testers let me know. Hochachtungsvoll, Bernhard R. Link

l rules for access through 'char'). But only in that example. In general memcpy might be optimized to some assignment causing a SIGBUS if gcc thinks it is save but it is not. (like a misaligned pointer to a struct where some member is accessed). Hochachtungsvoll, Bernhard R. Link

this is he result of "more clever", but mostly a side effect of better inlining that was not followed by making the warning code better to cope with such inlining. Hochachtungsvoll, Bernhard R. Link

sed will be errors. (The same with sizeof(void), which most likely only happens with p=malloc(sizeof(*p)) from macros). Is there already a warning against that (I cannot find any in the info page) or is there any chance to get such a thing implemented? Hochachtungsvoll, Bernhard R. Link

Re: Sine and Cosine Accuracy

nse of the word 'correct' range for those functions, or in any way sensible range for computations of those. Code like "if( x+y < 2*pi) return sin(x+y); else return(x+y-2*pi);" would really be useable to make me run around screaming, but naming any range smaller than some [-50pi,100pi] "valid" could really make me crazy...
