Thanks!  Working through this I found these problems:

this isn't "stable" the first of those symbols is choose.

this symbol can be missed entirely because min_label is > global_st_size_0.

this isn't stable, the second of local_in_global and global_outer is chosen.

I've attached a context diff of up-stream vs local (they are 
sufficiently different to make a unified diff harder to read). I'll see 
about mearing that !section and !file test.
