THS (The Holy Standard :-) ) 3.7.4.2/3 reads to me that for standard library
implementations the delete operators must be called in any case but return
immediately if the first argument is NULL =

In fact, I'm having trouble reproducing the problem when operator delete []
returns anything BUT NULL. It's as if, the actual call to operator delete []
is guarded by a NULL check. Now, if I'm RTHS (reading the

It seems that the bug triggers only when returning NULL in the new operators.
Returning something different ( tested with (void *)1 ) is a workaround for the
problem. Checking for not returning NULL in the

Ouch, this one seems particularly nasty to me... seeings as this isn't a
regression (at least from 2.95), I don't expect this to be fixed for 4.2. Is

Above, in operator new[], If WTF is false, returning NULL, I reproduce the
same error (missing call to class operator delete []). If WTF is true

Confirmed. 12.5/4 reads to me as if myclass::operator delete[] should be
called. Indeed icc doesn't call either user defined operator in the
array case. I think that's just a convergence of bugs, though.
This appears
