64-bit windows cabal.exe segfaults in GC
cabal.exe built with 64-bit windows GHC segfaults doing cabal configure or cabal install or probably something else.
This occurs *both* for cabal-install 1.18.0.2 built against Cabal 1.18.1.2 and for cabal-install 1.18.0.3 built against Cabal 1.18.1.3.
This occurs only for 64-bit build, 32-bit build is fine.
64-bit GHC-7.6.3 build is also fine.
During debugging I see segfault occurs inside evacuate somewhere near get_itbl call I guess.
If I make cabal.exe to not trigger some presumably bad GC compiling it with -rtsopts and running it as (for example) cabal +RTS -H256m -m50 -RTS ... the problem disappears.
