This only seems to occur in profiledbootstrap, e.g. x86_64-linux
--enable-checking=release profiledbootstrap, stagefeedback gnat1 fails, while
stageprofile and stage1 gnat1 work (and in normal bootstrap all of stage[123]
work).  The issue is somewhere in the Ada FE, already in the *.original dump
the difference is between if (0) vs. if (1) for the overflow check call.
Compared to normal bootstrap (also --enable-checking=yes,rtl) with
profiledbootstrap (--enable-checking=release) also shows:
+FAIL:  c34002a
+FAIL:  c460007
+FAIL:  c490001
+FAIL:  cc1221d
+FAIL:  cxa5a04
+FAIL:  cxg2001
+FAIL:  cxg2015
regressions, not sure if that is in any way relased to this issue.
