Jakub,
Can you check what --save-temps produces for g++.dg/tree-prof/partition1.C
in partition1.s on linux? Does it produce two sets of global statements as

This doesn't occur with gcc trunk on x86_64-apple-darwin10 but does for gcc
4.4.3. Perhaps backporting r151960 to avoid compact unwind code on gcc 4.4
branch for darwin10 would solve this.

r151960 doesn't eliminate the problem in gcc 4.4 branch.

This bug occurs in both gcc 4.4.3 and 4.4.2 on x86_64-apple-darwin10, however
it doesn't occur under x86_64-apple-darwin9. This may be a compatibility issue
with the FSF gcc unwinder code executed o

I wonder if the remaining failure on *86*-apple-darwin9 for PR41991 could also
be due to PR43099?

The last good build for powerpc-apple-darwin9 on regress was at r157263 so...
r157264
must be the offending commit. Is powerpc64-unknown-linux-gnu still
bootstrapping?

The miscompiled code in air.f90 is the subroutine SPECTOP. If I pull that
subroutine out into a separate file and compile it at -O3 without
-fgraphite-identity, the remainder of the code can be compiled

The offending optimization for the spectop subroutine at -O2
-fgraphite-identity appears to be -fstrict-overflow. I can compile...
gfortran -fgraphite-identity -O3 -fno-strict-overflow -c spectop.f90

Interestingly, I get...

Might this be related to PR42181 since it also involves problems with the
-fgraphite-identity -fstrict-overflow?

Does this fix resolve PR42181 as well or is that a different issue with
fgraphite-identity -fstrict-overflow?
