During Firefox build I get:

markus@x4 shell % /var/tmp/gcc_test/usr/local/bin/g++ -flto=4 -o foofo -O2
Unified_cpp_shell0.o ../libjs_static.a
In member function ‘init’:

--- Comment #1 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
Comparing the test suite results between r206040 and r206072+my_fix, the test
gcc.dg/tree-prof/pr52027.c (see pr52794) passes now, but the tests

g++.dg/tree-prof/partition1.C
gcc.dg/tree-prof/20041218-1.c
gcc.dg/tree-prof/crossmodule-indircall-1.c
gcc.dg/tree-prof/pr49299-1.c
gcc.dg/tree-prof/pr49299-2.c

fails with -m64.

The typical failure is

At this point I cannot say if these new failures are due to may fix or to some
recent commit.
