I'm looking for help with crazy-long compile times when using GHC with profiling. A source file at work has a single 10k line top-level definition, which is a CAF. With -prof auto-all or an explicit SCC, compilation runs for 8 hours on a fast machine with the heap growing to 13GB before being killed. Without profiling, it compiles in a few minutes.
The big CAFs are auto-generated and not of my making, so I'm hoping for a solution other than "stop making big CAFs".
We could take a look. Can you make a self-contained example that demonstrates the problem? Cheers, Simon
