The combination of this and the failure with -hc -hbdrag,void is preventing me from optimizing the program and it has a huge space leak somewhere.

Retainer profiling (-hr) doesn't currently work with STM. It is a bug, but I briefly looked into it and it's not a trivial fix so I left it. I'll file a ticket for it. Cheers, Simon
