They were probably at the exact same offset within each
module and the 2.9.0 linker could not flag them as

Shouldn't the linker have at least made a separate line in the map with the different addresses of all the shadowed variables? It seems to me that it behaved as if they were static when it should have been an error. I would have figured it out if I saw multiple lines with the same symbol.
