Hello, I'm using ghc 7.10.1 to compile OpenGLRaw which is now impossible with -O1 and -O2 due to "ghc : out of memory error" on a 4GB linux host.

With -O0 it uses 600 MB. <u></u><u></u></p>

I've been playing around with profiling GHC recently, so I thought I'd chime in with a pointer that might save people searching for the right docs - you could configure a cabal sandbox to work with multiple version of ghc, which I've found useful:<br>

Hi Richard,<br>
<br>
Thanks updating the ticket! What I did was: build GHC HEAD/7.8.4 with build flavor 'prof' then get the haskell-src-exts sources, install the dependencies and finally add +RTS -p -RTS to the cabal file and compile it, the resulting ghc.prof contains the profiling
information.<u></u><u></u></p>

I've pasted Michal's numbers in #9630, which seems like a good place to track this. Michal, would you mind fleshing out a bit precisely what you did to get those numbers? That would be helpful (though you've already been very helpful indeed in getting the data
together)!<br>

Thanks,<br>
