Hi Alexandre,
I just tried the same test on 4.6.2 compiler and 4.7.0 mainline. It fails in
exactly the same way as before. Can you test if the problem mentioned in this
has been fixed?

Thanks
Hari

Patch that fixes the bug on all affected targets

The introduction of option saving and restoring broke the special handling of
flag_var_tracking on the targets that delayed it.  This patch fixes it.
