With 4.4.0 20080523 [trunk revision 135791] the following fails on x86-64. It
was working with 2008-05-20-r135601.
$ gfortran -fprofile-generate -march=opteron -ffast-math -funroll-loops
-ftree-vectorize -ftree-loop-linear -msse3 -O3 mdbx.f90
$ ./a.out
$ gfortran -fprofile-use -march=opteron -ffast-math -funroll-loops
-ftree-vectorize -ftree-loop-linear -msse3 -O3 mdbx.f90
Valgrind shows for the latter:

mdbx.f90: In function "mstep":

If no -profile-generate'd data is available, there is no crash.
