Last night, Marge's merge requests failed several times because of a stats increase. compile_time/bytes allocated increased from x86_64-linux-fedora33-release baseline @ def47dd32491311289bff26230b664c895f178cc: Expected T9872a (normal) compile_time/bytes allocated: 1655471856.0 +/-1% Lower bound T9872a (normal) compile_time/bytes allocated: 1638917137 Upper bound T9872a (normal) compile_time/bytes allocated: 1672026575 Actual T9872a (normal) compile_time/bytes allocated: 1674083264 Deviation T9872a (normal) compile_time/bytes allocated: 1.1 % *** unexpected stat test failure for T9872a(normal) This happened on three separate attempts, each with a deviation of 1.1%: * https://gitlab.haskell.org/ghc/ghc/-/jobs/1247176 * https://gitlab.haskell.org/ghc/ghc/-/jobs/1247312 * https://gitlab.haskell.org/ghc/ghc/-/jobs/1247512 The reason I'm making an email out of this is that none of the individual patches that Marge is merging have this problem, but it seems to happen consistently when they are combined. You can see a list of patches by looking at the list of mentions on https://gitlab.haskell.org/ghc/ghc/-/merge_requests/9439. There were other problems with Marge's merges last night that I DO understand and have fixed. But this one, of course, is over my head. :) Maybe somebody can look at the list of patches and deduce something useful. Otherwise, I will continue monitoring Marge's progress, and try to find a smaller set of patches that can make it through. I'll prioritize getting the Javascript backend through. -Bryan
