So, can you from your build log paste the command to compile var-tracking.c
with the stage2 gcc and rerun it in the gcc subdir with additional
-fcompare-debug option?  It might be a -fcompare-debug issue (in that case
rerun with -save-temps option and attach var-tracking.i together with the exact
command line option used to compile it, or stage1 or stage2 cc1/cc1plus might
be miscompiled.
