In lib/vasnprintf.c the first two invocations of DCHAR_MBSNLEN
w = DCHAR_MBSNLEN (result + length, count);
look wrong, because the memory beyond result + length has not been
initialized at that point. This code handles the %ls and %lc directives.
The platforms where this code is enabled are Solaris and MSVC. And
indeed, once I add tests for the %ls and %lc directives, I see them
crash. On Solaris 11.4:

And similarly on MSVC 14.30.
The following patches fix the problem and add the unit tests.
2024-06-18 Bruno Haible <[email protected]>
u*-vasnprintf tests: Add tests of %ls directive.
