Yes, I just ran into this problem with a snapshot from yesterday.

No, I don't.  Its odd because the string includes are present:

find -name string
./am180x-evm/usr/include/c++/string
./am180x-evm/usr/include/c++/debug/string

Using built-in specs.

I noticed --with-gxx-include-dir=/usr/include/c++, but other builds
