what will happen after i use free()???

[Mark McIntyre]

Richard's error, I think, was in assuming we were talking about
different calls to malloc() returning their results in different
registers. Reading about the M68K wouldn't clear that up.

No, but it might prove instructive nevertheless!

The only other place in the rest of the post that would have
clarified was one word off from confirming the 'yes' and, since it
was sequentially later than the 'yes', was easily misread.

Yes, yes, yes. I do admit that my original post was messed up. My
subsequent ones were (I hope) quite clear, but that didn't seem to be
good enough.

I'll drop it here.

Not a chance with this crowd. They have their teeth sunk into you,
and will worry this nonsense into the ground and back several times
before letting it die.

OK, I think where the disconnect is.

We both agree that casting the return from `malloc()` is a Bad Thing.

Where we seem to disagree seems to be where the UB comes from if
<stdlib.h> is not included.

No.

You seem to think it's the cast that does it.

No, the cast hides the error and the diagnostic threout.

I, OTH, think that UB has already happened *before*, and independently
of the cast. Cast may just hide the diagnostic that may have warned
you of the problem. (FWIW, it does seem that a few other people here
share my view.)

OK. You win.

In what sense does he "win"? He clearly said previously that the cast
causes undefined behavior. Now he's changed is story, but without
acknowleding his error.

I interpret Vladimirs posting as "I'm tired of this pointless
argument".

Exactly.

This abominable thread already had my head spinning from trying to
figure out what /is/ his POV after all.

[I also suspect he changed his mind but wwouldn't admit to it.]

BR, Vladimir

There was a young man of Ostend
Who let a girl play with his end.
She took hold of Rover,
And felt it all over,
And it did what she didn't intend.
