mmap 131072 bytes at (nil): Cannot allocate memory #293

Open newhoggy opened 3 years ago

newhoggy commented 3 years ago

I am getting this error in Github Actions:

doctests: mmap 131072 bytes at (nil): Cannot allocate memory
doctests: Try specifying an address with +RTS -xm<addr> -RTS
doctests: internal error: m32_allocator_init: Failed to map
    (GHC version 8.10.3 for x86_64_unknown_linux)
    Please report this as a GHC bug:  https://www.haskell.org/ghc/reportabug

This has been reported to GHC as well: https://gitlab.haskell.org/ghc/ghc/-/issues/19421

This is easily reproducible from this commit: https://github.com/input-output-hk/cardano-ledger-specs/pull/2147/commits/694a33f04a27b53b0cb57e42f3ad0affbed26625

The error can be seen here: https://github.com/input-output-hk/cardano-ledger-specs/runs/1958540147?check_suite_focus=true

It should be possible to reproduce it by forking the project and attempting to build this commit in Github Actions in the manner described by the .github/workflows/haskell.yml file.

On MacOS, there is also an error, but it is very different:

This could be caused by:
   * Loading two different object files which export the same symbol
   * Specifying the same object file twice on the GHCi command line
   * An incorrect `package.conf' entry, causing some object to be
     loaded twice.
