need help finding the patch for Bugzilla 31947/34809/33195

[JB]

After happily using gcc-4.2 for about 7 years, some recent code changes 
have exposed bug 31947 (which has two dups)

I'm investigating the options to address this, and have found that 
-fno-inline works in my situation.  An alternate solution would be to 
patch the compiler, but I've been unable to identify the change(s) 
associated with fixing this problem.  For this particular code base, I'm 
stuck on 4.2, and may even have trouble using a patched compiler.   But 
I didn't expect to get stuck trying to find the patch.  I've browsed the 
repo from that time frame and searched current sources for any mention 
of any of these bugzilla numbers to no avail.  Thus my request for help.

Thanks,
John
