x86_64 ldd hangs running on a DLL

[Rodney Brown]

$ uname -a
CYGWIN_NT-10.0-19045 X 3.4.6-1.x86_64 2023-02-14 13:23 UTC x86_64 Cygwin
$ ldd --version
ldd (cygwin) 3.4.6

As with "ldd freezes" https://sourceware.org/legacy-ml/cygwin/2015-07/msg00314.html , cygcheck works,
not only for Cygwin DLLs and ldd hangs needing the xterm to be closed, though it can interrupted when run
under strace, or did. Strace now is segfaulting.

Did Corinna's fix for i686 not end up in the x86_64 code?
