Ugh.  I don't remember the details in gcc 4.7 - the way streaming works has
completely changed since then (well, the basics are still in
tree-streamer-{in,out}.c)

So you are on your own debugging where the info gets lost.  Did you try setting
breakpoints on the streaming of your flag or add printfs?


Okay. We will explore various options (including the possibility of moving to gcc 5.1).

Thanks a lot for your suggestions.

Uday.
