@izgzhen Is this from a clean build? Linux bots on Travis seem to be happy.

[alpmestan]

I'm also developping Hadrian from Linux and I have not seen this error.

[snowleopard]

Note that according to a recent AppVeyor build, HsInstances takes the longest time to build. Could GHC somehow fail to build it? Can you try to simply rerun Hadrian?

[izgzhen]

sorry, I redo everything and it looks like a false positive
