Any 64bit big-endian cpu with strict alignment is broken without '''-xmemalign=4s''' (the immediate workaround) The default for all v9 architectures is '''-xmemalign=8s'''. However, our goal should be to allow fast aligned code and not to skip this with a compiler relaxement. {{{ t@1 (l@1) stopped in PF_fetch_integer at line 1076 in file ""pf_items.c"" 1076 ASSERT_ARGS(PF_fetch_integer) (dbx) step t@1 (l@1) stopped in PF_fetch_integer at line 1078 in file ""pf_items.c"" 1078 if (!pf || pf->fetch_iv == NULL) (dbx) print *(*stream) **stream = 4 (dbx) step t@1 (l@1) stopped in PF_fetch_integer at line 1079 in file ""pf_items.c"" 1079 return *(*stream)++; (dbx) print *(*stream) **stream = 4 (dbx) step t@1 (l@1) signal BUS (invalid address alignment) in PF_fetch_integer at line 1079 in file ""pf_items.c"" 1079 return *(*stream)++; (dbx) print *(*stream) **stream = 35 (dbx) print *stream *stream = 0x100000dec }}} '''0x100000dec''' is not properly aligned.

The fix for 1.0 will be a hints file update to add -xmemalign=4s to cc_flags, the goal for 2.6 will be a --64bitcompat argument to parrot to create 8-byte aligned values on 32-bit, not 4-byte as now.
