I'm running latest Cygwin under Windows XP Pro (SP2, with all updates). 
  I installed all the Singular packages via Cygwin Setup.

After I start cygwin with its bash shell, command

   Singular

gives error:

   Singular " signal 11 (v: 3001/2005111410):
   Segment fault/Bus error occurred (r:1136744764)
   Please inform the authors
   trying to restart...

(The number after "r:" changes depending on what else is running in 
windows.)  But Cygwin never recovers, and it freezes.

At first I tried uninstalling Singular, downloading the Singular 
packages again, and re-installing; same error.  I completely uninstalled 
Cygwin, downloaded Cygwin again including the Singular packages, and 
re-installed.  Same error.

On the other hand, if I go to the subdirectory lib\Singular of the main 
cygwin directory and double-click Singular.exe, then Singular does run, 
in a DOS command prompt window (although I see message "cannot open 
`standard.lib'".

So the bug seems to be somewhere in the interface between Singular and 
cygwin.  Any ideas of how to proceed.  (I did report this bug on the 
Singular web site a couple days ago but have had no response.)
