Sorry, I won't get around to compile gcc (never done that yet) and test it.

--- Comment #6 from Dominique d'Humieres <dominiq at lps dot ens.fr> 2012-07-04 12:07:15 UTC ---
g++.dg/other/pr53811.C fails on x86_64-apple-darwin10 with -m64:
FAIL: g++.dg/other/pr53811.C -std=gnu++98 (internal compiler error)

FAIL: g++.dg/other/pr53811.C -std=gnu++11 (internal compiler error)
FAIL: g++.dg/other/pr53811.C -std=gnu++11 (test for excess errors)
The ICE is
Excess errors:
/opt/gcc/work/gcc/testsuite/g++.dg/other/pr53811.C:29:1: error: insn does not
satisfy its constraints:
(insn 3 2 4 (set (reg:DI 59)

] UNSPEC_GOTOFF))) 62 {*movdi_internal_rex64}

Should I open a new PR?
Note that ' -mcmodel=large' seems to have issues on x86_64-apple-darwin10: see
pr50077.

Yes, please. I will wait with the 4.7 backport until new PR resolves.

TBH, -mcmodel=large is currently an overkill, but fixes are fairly trivial
(pushing address to temporary reg).
