ghc crash on arm with -j2: internal error: scavenge: unimplemented/strange closure type
ghc: internal error: scavenge: unimplemented/strange closure type 0 @ 0xac103240
(GHC version 7.10.1 for arm_unknown_linux)
Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug
Aborted
I can consistently get either this crash, or a segfault from ghc, building git-annex on an arm system. Seems about 50/50. In either case, it crashes either before ghc has printed out any "Compiling" lines, or within the first 1 or 2 files compiled.
I got lucky and found out a way to avoid the crash.. cabal was passing -j2 to ghc. If I remove the -j2, the build proceeds without a crash.
The hardware is a CubieTruck arm board, with 2 gb of ram, and 1 cpu core, running Debian armel unstable, with kernel 3.4.103.
I was able to use cabal to install the entire dependencies of git-annex, all the way up to yesod, which takes hours on this hardware, and all that built ok.. so I think the hardware is pretty stable, but still cannot really rule out a hardware problem.
Happy to debug further, although this machine is a bit resource constrained to do things like building ghc on it.
ghc 7.8.4 and 7.10.1 both crash the same way.
