But don't our windows buildbots do this for us? Surely! That's what they are for. Me bisecting on my little laptop is not a very happy situation. Don't we have better technology?

Same here, can't reproduce on 64bit Windows 10. Edward Excerpts from Thomas Miedema's message of 2015-10-26 17:54:35 -0700:

I can not reproduce this on 64bit Windows, a9c93bdd8b027d6de09a3eada7721e7fd2d3e050 builds succesfully with flavour devel2.

* Which build flavour are you using? Any other mk/build.mk settings? * 32bit or 64bit? * Output of `git status` (i.e. did you 'git submodule update'? In case that fixes it, I suggest you use git pullall https://ghc.haskell.org/trac/ghc/wiki/WorkingConventions/Git/Submodules#gitp... for all your pulling needs) * Try `make maintainer-clean`. * In case you use llvm, note that HEAD needs llvm-3.7 now.

Gurgah. GHC is broken on my windows laptop. See below. Anyone have any ideas? Frustrating.

Oddly the symbol is defined in the .exe

bash$ nm inplace/bin/ghc-stage2.exe | grep stg_upd_frame

02c248e0 T _stg_upd_frame_info

This is admittedly on a branch that I have modified; but I have only modified stuff in the front end, nothing in the RTS etc. I suppose I will try to build a unmodified HEAD too.

can anyone help? Thanks!

Simon
