Comment (by erikd):

 Tried once again to debug this using GDB.

 {{{
 $ gdb --args inplace/bin/ghc-stage2 +RTS -V0 -RTS --interactive
 (gdb) break main

 (gdb) break main
 Breakpoint 1 at 0x93cd8
 (gdb) r
 Starting program: /home/erikd/Git/ghc-upstream/inplace/lib/bin/ghc-stage2
  -B/home/erikd/Git/ghc-upstream/inplace/lib +RTS -V0 -RTS --interactive
 [Thread debugging using libthread_db enabled]
 Using host libthread_db library "/lib/arm-linux-
 gnueabihf/libthread_db.so.1".

 Breakpoint 1, 0x00093cd8 in main ()
 (gdb) while 1
  >x/i $pc
  >stepi
  >end
 }}}

 and it crashes in a at least 3 or 4 different ways on different runs, none
 of them even remotely like the way it crashes outside GDB.
