Bug in sgicc version 0.01.0-13

["Robboy, David G" <david.g.robboy@xxxxxxxxx>]

Compiling the attachted program with -O3 using sgicc version 0.01.0-13, the
function "bar" is optimized down to no code at all. The code should access
the volatile field in  memory on each  iteration of the loop.

Is there a later release of sgicc in which this bug is fixed?
