Since Michael said WIN32-specific tests and mentioned log pattern, he is
referring to TAP tests. You can add src/test/modules/test_backtrace that
exercises this code path.

I didn't test your patch but I'm wondering if we could add an abstraction here.
I mean invent pg_backtrace() and pg_backtrace_symbols() that maps to the
current functions (Unix-like). On Windows these functions are mapped to
win32_backtrace() (that encapsulates CaptureStackBackTrace()) and a new
win32_backtrace_symbols() (that encapsulates the rest of the code). There
Windows-specific functions should be added to src/port -- my suggestion is
win32backtrace.c. Besides that you have to adjust backtrace_symbols in both
configure.ac and meson.build so it runs the code path inside
HAVE_BACKTRACE_SYMBOLS.
