Comment (by slyfox):

 The problem in comment:#21 was in ASL/LSL implementation:
     https://github.com/vivier/qemu-m68k/pull/7 should fix it (lightly
 tested)

 With Phab:D1975 applied ghc-stage2 still SIGSEGs.

 Current run of regression tests fails the following ~200 tests:
 {{{
 $ make fasttest TEST_HC=$(pwd)/inplace/bin/ghc-stage1 THREADS=12
 # testsuite/mk/ghcconfig_*.mk needs a fix in WORDSIZE, GHCI support
 }}}

 Many of them are not real problems (like missing TH annotation around
 tests, perf failures)
 but some are real failures.

 Investigating.
