--- Comment #1 from Iain Buclaw <ibuclaw@gdcproject.org> ---
Problem is that in the operation:

a = a >> 1;

'a' is promoted to an unsigned integer for normal operations before the final result being downcasted back.

So we get the following sequence.

a           => -1
cast(uint)  => 4294967295
a >> 1      => 2147483647
cast(short) => -1
