[Bug c++/38228] New: ICE when abusing std::function

[aep at exys dot org]

hi, i just tried this for fun (yes i'm aware it doesnt work :P):

#include 
#include 

struct foo 
{ 
void bar(){std::cout<<"hi"<  funct=((f).*(a));
}


and it results in:

[Bug c++/43789] New: warn about pointer aritmetic in sizeof

[aep at exys dot org]

Gcc already contains useful warnings for almost certainly incorrect code. I
propose adding a warning when pointer arithmetic is used inside sizeof, that
degrades an array to a pointer.


char a[]="blabla";
sizeof(a-1);

If the intention was _actually_ to get sizeof(char), it is a really awful way
to do so. Instead, it is very likely a typo.
Hence i suggest adding a warning.
thanks.
