Commit Message

backtrace: handle missing dladdr symbols

On macOS, dladdr() can report success for a known image while leaving
dli_sname NULL. Passing that NULL to __cxa_demangle() and then caching
the name can crash when fiber.info() collects a backtrace.

The macOS dladdr(3) manual documents this in its ERRORS section:

> If the image containing addr is found, but no nearest symbol was found,
> the dli_sname and dli_saddr fields are set to NULL.

Treat a frame without a symbol name as unresolved before calculating
its offset or invoking the demangler. Add a macOS shared-library
fixture whose stripped function has no symbol visible to dladdr().

Part of #13330
