Concrete Limiter - not stopping clipping

I have done several tests now, and the results are consistent:
 
Using Concrete Limiter in ProChannel, and setting the out ceiling to -0.1 db, it consistently goes over if pushed hard enough.
 
Maybe it's just me, but it seems that "concrete" in this case should mean that there are no peaks over this level.
 
Can anyone comment or replicate?
 
Note: this was done taking a 44.1kHz mix and upsampling it to 96 kHz.

Last person who reported this actually had his ProChannel pre fx bin and was running some fx after the CL by accident.

Is the CL's own meter reporting this or the track meter?

I was going to recommend the same thing.  

Did you check if you had plugins in the FX bin and if PC is post FX bin?

No automation on the bus level; no efx post the Concrete Limiter.
 
The mystery remains.

Almost every limiter when pushed over its limits will clip. Especially when the attack and release settings are wrong for that audio. What makes this limiter different from the others, especially the  better limiters that are out there??
 
To solve it, Back off your signal or use a better limiter and one that has ISP detection and oversampling.

Every "concrete" limiter I've owned has been run into the red and digital clipping on occasion. However, I agree totally with CJaysMusic that if you're slamming your signal into it hard enough to achieve that then it's probably way too hot and needs taming.
Talking of slamming limiters, I find psp's Xenon is really quite outstanding under harsh punishment. It's probably too cpu hungry to throw on everything though.
