[issue16143] Building with configure option "--without-doc-strings" crashes first time through PyUnicode_DecodeUTF8Stateful

[Gregory Andersen]

New submission from Gregory Andersen:

Seems unicode_empty is still NULL at this point.

A gdb backtrace from an x86_64 build.  Reproduced on i686 and mips build as well.

Program received signal SIGSEGV, Segmentation fault.
