1) Is it safe to allocate an array of 0 objects?
2) If yes: has anyone experienced that there is
a bug in MSC 6 (12.00.8804) that does not allow
such allocations?

Yes (the standard says so in section 5.3.4 paragraph 7).

I just tried the following code with that compiler:
#include <cassert>
int main()
{
assert(new int[0] != 0);
return 0;
}
It worked for me. Also I tried and failed to find any report of a bug
of this nature in the MS Knowledge Base. Are you doing something
different?

Yes, section 5.3.4 paragraph 7 says that when the expression (i.e.
size) is zero, the allocation function is called to allocate an array
with no elements, and the returned pointer is non-null.

Nope... but then again, I don't use MSC :)
