Could you please try to find out where exactly the problem is?

You can do a binary search on the object files compiled with the
options that result in a working binary by linking them with the ones
that result in a non-working binary.
Maybe you can find a single file that gets miscompiled, and then 
find out what function in that file gets miscompiled.
