Re: ghc: out of memory error while compiling huge "let"

I found that GHC is O(n^2) in terms of the number of lines in a do block, so by splitting up a huge 1000 line do block in to 10 x 100 line do blocks, I was able to get a massive compile time boost. Perhaps you might have similar luck with let's.

Didn't we fix the do-block blowup? Certainly do submit a bug report if you find GHC going O(n^2) or worse on any particular construct, usually we can find the culprit and fix it. Cheers, Simon
