 a process

[Message part 1 (text/plain, inline)]

Starting today (2014/09/26) when I issue a command that needs to fork a
process such as dired I get the message in the terminal window:
      0 [main] emacs-w32 816 child_info_fork::abort: 
C:\cygwin\bin\cygharfbuzz-0.dll: Loaded to different address: 
parent(0x340000) != child(0xF80000)

I am running Windows 8.1 using cygwin and
GNU Emacs 24.3.93.1 (i686-pc-cygwin) of 2014-08-15 on fiona

This usually means you need to run rebaseall.  See

When I do this, I get:

$ /bin/rebaseall
/usr/lib/perl5/5.14/i686-cygwin-threads-64int/CORE/cygperl5_14_2.dll: 
skipped because nonexistent.
/usr/x86_64-pc-cygwin/sys-root/usr/bin/cygcrypto-1.0.0.dll: skipped 
because wrong machine type.
/usr/x86_64-pc-cygwin/sys-root/usr/bin/cygssh2-1.dll: skipped because

wrong machine type.
/usr/x86_64-pc-cygwin/sys-root/usr/bin/cygz.dll: skipped because wrong 
machine type.
$

and my emacs behavior is even worse.

These are harmless warnings.

Then you should follow up on the Cygwin list.  I'm pretty sure this is a 
Cygwin issue and not an Emacs bug.  When you do follow up, please attach 
cygcheck output as requested at http://cygwin.com/problems.html, and 
please give the simplest possible recipe for reproducing the problem 
(starting from "emacs -Q").  Also, it might be useful for you to 
compress and attach the output of "rebase -is"; the address at which 
cygharfbuzz-0.dll is loaded looks surprisingly low to me.  This makes me 
think of another thing you could try: Move the rebase database 
/etc/rebase.db.i386 out of the way and then rerun rebaseall.

This sounds like it's most likely a Cygwin bug, so I'm closing this bug
report.
