Note to bearophile: The case where the number of elements is LESS than the
array size (bug 3849) is quite different. Note that, for example,
int [3] x = [ 2: 15]; is currently legal.

This patch is slightly more general, in that it covers the cases like
  int[3] toomany = [ 2: 13, 1];

PATCH: init.c line 343 (in ArrayInitializer::semantic()).


if (length == 0)
error(loc, array dimension overflow);
if (length  dim)
dim = length;
}

+if (t-ty == Tsarray)
+{
+size_t edim = ((TypeSArray *)t)-dim-toInteger();
+if (dim  edim)
+{
+error(loc, array initializer has %d elements, but array length is
%d, dim, edim);
+return new ExpInitializer(loc, new ErrorExp());
+}
+}
unsigned long amax = 0x8000;
if ((unsigned long) dim * t-nextOf()-size() = amax)
error(loc, array dimension %u exceeds max of %ju, dim, amax /
t-nextOf()-size());

Regarding bug 3849, I did put both things in the same bug report because:
- they are strongly semantically related, the compiler has to refuse fixed
sized literals with a number of items different from the number specified on
the left (this is true for nD arrays too);
- The cause of this ICE can be related to the lack of tests over the number of
items in the literal compared to the number on the left. So fixing one bug can
even fix the other too, or it can be very quick to fix one when you fix the
other. That's why I have not originally marked that as enhancement.
