@Marek: The callgraph checking error is correct.
If you disable it, you will likely see duplicate assembler names in GAS. And
that's the error that 2 symbol names clash.

Indeed, there are two lambdas, but I think C++ FE should assign them
different symbol names.

c++: mangling of lambdas in default args [PR91241]
In this testcase, the parms remembered in LAMBDA_EXPR_EXTRA_SCOPE are no
longer the parms of the FUNCTION_DECL they have as their DECL_CONTEXT, so
we
were mangling both lambdas as parm #0. But since the parms are numbered
from right to left we don't need to need to find them in the FUNCTION_DECL,
we can measure their own DECL_CHAIN.

(write_local_name): Use list_length for parm number.
