Comment (by erikd):

 By hacking `configure.ac` I managed to build GHC with `-fsanitize=address`
 passed to GCC.

 Absolutely, positively, 100% certain that something is wrong:

 {{{
 $ inplace/bin/ghc-stage2 --interactive
 ASAN:SIGSEGV
 =================================================================
 ==7051==ERROR: AddressSanitizer: SEGV on unknown address 0x00000000 (pc
 0x00000000 sp 0xbeffe5f0 bp 0x37dffd15 T0)

 AddressSanitizer can not provide additional info.
 SUMMARY: AddressSanitizer: SEGV ??:0 ??
 }}}

 `ghc-stage2` compiled with AddressSanitizer on `x86_64/linux` does not do
 the above.

 Unfortunately, while AddressSanitizer has found a problem, it doesn't
 provide any new information. I suspect it doesn't know enough about GHC's
 run time and calling conventions.
