Just ESCAPED, see below.
r137251
derefaddrtmp.893 = { ESCAPED }
derefaddrtmp.894 = { NONLOCAL }
this = { PARM_NOALIAS.895 }
PARM_NOALIAS.895 = { ANYTHING ESCAPED NONLOCAL }
D.3410_6 = same as thread_data
thread_data = { ANYTHING }
D.3411_7 = same as thread_data
D.3417_13 = { ANYTHING }
r137252
derefaddrtmp.893 = { ESCAPED }
derefaddrtmp.894 = { NONLOCAL }
this = { PARM_NOALIAS.895 }
PARM_NOALIAS.895 = { ESCAPED NONLOCAL }
D.3410_6 = same as derefaddrtmp.893
thread_data = same as derefaddrtmp.893
D.3411_7 = same as derefaddrtmp.893

None that I could spot by scrolling through 1000+ lines of differences.
