profiling and backtracing blues

[Ranjit Jhala]

Hi all, 

I'm trying to use the nifty backtracing mechanism in GHC 74.
AFAICT, this requires everything be built with profiling on), 
but as a consequence, I hit this:

	"You can't call hscCompileCoreExpr in a profiled compiler"

Any hints on whether there are work-arounds?

Thanks!

Ranjit.
