I know they work fine in 2.3.1: http://www.freepascal.org/testsuite/cgi-bin/testsuite.cgi?action=1&run1id=30179&run2id=30188&noskipped=1&failedonly=1

The only difference is that apparently profiling doesn't work with  
regvars on.

I'm not aware of any related fixes which have not been merged to the  
fixes branch, but I don't know whether all of those fixes were merged  
back before 2.2.0. I guess they should work fine there, though.

They're not enabled by default in 2.2.2 either, for that matter.
