I'll address this in a follow-up. I wanted to address the regression you 
found:

This is happening because match_transparent_type in symtab.c is assuming 
GLOBAL_BLOCK, even though the desired block type is passed in.

With the simple patch below, the regression is gone.

May I commit this? [It causes no regressions on x86_64 linux.]
