C66xx optimizer bug at higher optimization levels

I am using CGT 7.3.1.  If I compile the attached file using -mv6600 -O2 -DSIZE=24, the time it takes to compile roughly doubles when I increase SIZE by one -- for example, 15 seconds when SIZE=24, 29 seconds when SIZE=25, 57 seconds when SIZE=26, and so forth (most of the time seems to be spent in opt6x).  My desired value for SIZE is large enough to put the compile time in years, assuming the pattern holds.  If I compile just using -O2, or with -mv6600 -O1, it finishes quickly.

Is this a known problem?  Is there a better workaround than to put this function in its own file and reduce the optimization level for that particular file?  (Please pardon it being attached as a .txt; the forum software rejected a .c extension.)

struct data
{
	int GBi[SIZE];
};

int min_gbi_(struct data *const input[], int count)
{
	int min_gbi = 2048;
	int it;
	int ix;

	for (it = 0; it < count; ++it)
	{
		for (ix = 0; ix < SIZE; ++ix)
		{
			if (min_gbi > input[it]->GBi[ix])
			{
				min_gbi = input[it]->GBi[ix];
			}
		}
	}

	return min_gbi;
}
