[ANNOUNCEMENT] Updated: xorg-server-1.17.1-3

[ANNOUNCEMENT] Updated: xorg-server-1.17.1-3

[Jon TURNEY]

The following packages have been updated in the Cygwin distribution:

*** xorg-server-*1.17.1-3

These packages contain XWin and the other X.Org X11 servers.

The following cygwin-specific changes have been made since 1.17.1-2:

* Fix build with Cygwin 2.0.0
* Crash reporting improvements using new features of Cygwin 2.0.0
* Update builder email for cygwin-xfree list deprecation
* Capture xkbcomp exit status, stderr and stout to log
* Clarify authorization failure reason strings sent back to the client
* Generic handling of Macintosh keyboard layouts
* Correctly check if window title already contains hostname when 
WM_CLIENT_MACHINE is a FQDN

NOTEWORTHY CHANGES IN 1.17
==========================

The creation of indirect GLX contexts is now prohibited by default.  The 
+iglx option is required to allow them.  See [1] for more information on 
possible OpenGL configurations.

'-nolisten tcp' is now the default, so the server only accepts local 
connections on a unix domain socket.  A '-listen' option has been added 
which can be used to restore the previous behaviour.

I'm finding, on three different 64-bit Cygwin systems, that the server 
dies shortly after starting.  I'm attaching XWin.0.log from one of them. 
  The log from a 32-bit Cygwin install on the same machine starts the 
same but then continues with

[440201.140] winPointerWarpCursor - Discarding first warp: 640 512
[440201.140] (--) 8 mouse buttons found
[440201.140] (--) Setting autorepeat to delay=500, rate=31
[...]

The problem goes away if I revert to 1.17.1-2.  Let me know if there's 
further information that I can provide.

That is rather mysterious and disappointing.  I can't reproduce this.

Does this occur if you run XWin directly?

If so, could you perhaps upload a strace somewhere, please?

Thanks.

This ends with ...

--- Process 2996, exception c0000005 at 0000000180155C82

and...

$ addr2line -e /usr/lib/debug/usr/bin/cygwin1.dbg 0x0000000180155C82
/usr/src/debug/cygwin-2.0.1-1/winsup/cygwin/malloc.cc:4753

... which is somewhere inside free().

I don't quite understand why cygwin's exception processing doesn't then 
catch that exception and raise a SIGSEGV.

However, I did a bit more staring at the changes in 1.17.1-3 and I did 
find a nasty bug in some code which uses the heap.  I've uploaded a 
snapshot [1] with a possible fix, please test that if you can.

No problem.  Thanks for testing, and thanks for reporting the bug!

I've uploaded 1.17.1-4 with this fix.
