The use in tree-ssa-loop-niter.c is really trying to skip out on inferring loop bounds from pointer to structure accesses in the case of things like:

struct a { char foo[1]; };

struct a *b = malloc (sizeof (struct a) + 100); b->foo = "I like candy!"

Since we have to keep this working:)

We do?! Storing a pointer value to a char variable has never worked very well so far!

I was shorthanding it, you know what i meant :)

heh, yeh, I knew.

But I see so many lines like that in C programs written by people who think they're writing in C++ [*] ....

[*] Or BASIC, even more likely!

Can't think of a witty .sigline today....
