Up to this point, I believe you only used mac_breakpad_symbols when you where
already conditionally inside of OS=="mac".   I believe this may be uninitialized
on other platforms.
I am not sure it is legal to assume that the OS=="mac" will safely prevent
mac_breakpad_symbols from being dereferenced at the same unfolding depth.

                 # A real .dSYM is needed for dump_syms to operate on.
                 'mac_real_dsym': 1,
               },
             }],
