Hello,

There appears to be a problem with the 'RPM' utility, 
as it produces no output, not even for --version or --help.
It appears all dependencies are installed.  I could not 
find any reports on this (bug?) in the lists, so here 
are the details.

- 'rpm --version' reports nothing.

- 'strace -o rpm_strace.out rpm' produces the following 
Windows pop-up error dialog:

   -----------------
   rpm.exe - Entry Point Not Found
   -----
   The procedure entry point poptSaveInt could not be 
located in the
   dynamic link library cygpopt-0.dll.
   -----------------

- The strace output is:

   Process 5816, exception c0000139 at 77431D82

- Rebase had no effect.

- Tested in mintty and X with same result.

- Tested with the 1.7.27-2 configuration as well as the 
latest snapshot (20140108 16:52:21) with same result:

   CYGWIN_NT-6.1-WOW64 Win7main 1.7.28s(0.271/5/3) 
20140108 16:52:21 i686 Cygwin

- OS: Windows 7 Professional 64-bit w/SP1, on Intel 
core-i7.
   Tested on two different systems with varied 
application and antivirus installed.

- cygcheck.out and strace.out attached.

NOTE: The previous version of RPM, v4.1-2, appears to 
work fine.

Best regards,
Ken
