Perf builds of HEAD seem broken on Windows
When building HEAD (currently at ed37027f) with a perf flavour with Hadrian on Windows, I seem to obtain a completely broken GHC.
git clean -xfd
./boot && ./configure --enable-tarballs-autodownload
hadrian/build.bat -j --flavour=perf
I get a GHC that seems unable to do anything. ghc --version
stalls for a bit and then returns silently, same with ghci
. ghc-pkg
segfaults:
$ "_build/stage1/bin/ghc-pkg.exe"
Access violation in generated code when executing data at 0x7ff75be6dd58
Attempting to reconstruct a stack trace...

Trying to run the test-suite fails with the error
Exception: Command failed: ['"C:/Haskell/ghc/primops/_build/stage1/bin/ghc-pkg.exe"', 'dump']
presumably because ghc-pkg
segfaults.
Development flavours seem to not be affected; I've been building devel2
ghcs without issue.
