Long rules sets not accepted with FATAL: Internal error in rule_run #4401

[blb4github]

I'm experiencing problems with long rules sets. attached 3 rules sets:

The rules set 20241218o_rc can be loaded:
Heishamon_rules20241218o_rc.txt

The rules set 20241218p_rc is the same as 20241218o_rc but with some additional logic in TaShift:

if #allowHeatDelta == 1 then
	$HD = -1;
	if #CompRunTime > -1 && #CompRunTime < 3 then
		$HD = #HeatDelta + 5;
	elseif #CompRunTime > 20 && #CompRunTime < 25 then
		$HD = #HeatDelta;
	end
	if @Heat_Delta != $HD && $HD > 0 then @SetFloorHeatDelta = $HD;end
end

this rules set is not accepted, it ends with error:

rule #8 was executed in 1355 microseconds
bytecode: 404/404, heap: 80/80, stack: 4/84 bytes, varstack: 1032/1048 bytes

If I take out some lines in rule syncOT, completely not related to the addition above the rules set is accepted again, the lines with -- in front are taken out:

		if #CompState > 0 then
			?flameState = 1;
			if @Heat_Power_Consumption > 0 then ?chState = 1; else ?chState = 0; end
--			if @DHW_Power_Consumption > 0 then ?dhwState = 1; else ?dhwState = 0; end
--			if @Cool_Power_Consumption > 0 then ?coolingState = 1; else ?coolingState = 0; end
		else
			?flameState = 0;
			?chState = 0;
--			?dhwState = 0;
--			?coolingState = 0;
		end

already tested splitting TaShift again?

yes, I tested it as well with TaShift splitted, it gives the same error:
