Summary of Problem

Source Code:

var lo = -0x1:int(8);
var hi = 0x7e:int(8);
writeln((lo,hi));

var A : [lo..hi] int;
writeln(A);

(-1, 126)
$CHPL_HOME/modules/internal/ChapelBase.chpl:960: error: Attempting to allocate > max(size_t) bytes of memory

I added a writeln(size) to ChapelBase.chpl, which reports -128.

It works if hi is 0x7d, reporting a size of 127.

Associated Future Test(s):

None yet.
