Hello,

I'd like to compile ghc-7.8.2 with DynamicGhcPrograms disabled (on
64-bit linux).  I downloaded the source tarball, added

DYNAMIC_GHC_PROGRAMS = NO

to mk/build.mk <http://build.mk>, and did ./configure && ./make.

ghc builds and everything seems to work (cabal installed a bunch of
packages, ghci seems to work), however whenever I try to run Setup.hs
dynamically (either 'runghc Setup.hs configure' or loading it with ghci
and executing 'main') it dumps core.  Compiling Setup.hs works, and
nothing else has caused ghci to crash either (this email is a literate
haskell file equivalent to Setup.hs).

Building with DYNAMIC_GHC_PROGRAMS = YES works properly.

With that in mind, I have a few questions:

  How should I compile a non-dynamic ghc?
  Is this a bug in ghc?

I think you are running into this: https://ghc.haskell.org/trac/ghc/ticket/8935

It took me a *long* time to track that one down.  I still don't know what the root cause is, because I don't understand the system linker's behaviour here.
