"new T[0]" looks like defined behavior to me.
[expr.new] 5.3.4 -7-
When the value of the expression in a direct-new-declarator is zero, the
allocation function is called to allocate an array with no elements. The
pointer returend by the new-expression is non-null. [Note: if the library
allocation function is called, the pointer returned is distinct from the the
pointer to any other object.]
===
cp/init.c even quotes that section in a comment before giving the warning.
cp/init.c goes on to say "However, that is not generally useful, so we issue a
warning". new T[0] is valid C++ and here is a useful case.
