"Caught signal 11 (Segmentation fault). Server aborting"
So far I've only been able to duplicate this when tunneling Eclipse. I
tried writing a simple java program that creates a JFrame window but
could not replicate the crash with anything smaller (sorry!). The
problem exists in the two versions I tried: Eclipse 3.6 and 4.2.
Although the error message pops up, Cygwin/X doesn't actually terminate
until the error window that reports the segfault is closed. X continues
to work if I ignore it, however all of the newly created windows do not
have any titlebars or frame borders.
This problem does NOT occur when running with either a root window or
with the '-rootless' option.
I've attached the XWin backtrace.

I'm afraid your diagnosis is a bit speculative.

converting the X11 icon to a Windows icon, and then not checking properly for
that failure.
I've applied a fix to address the immediate problem of not checking for the
failure, and I've uploaded a snapshot at [1]. Perhaps you could try that and
see if it fixes the issue for you? If it does, I would also be interested to
know how the icon for the window which was causing this issue appears.

This is because the crash is occurring in the window manager thread, not the
server thread.

Yes, this solves the crash problem (thank you!).

I've attached some screenshots of the taskbar and titlebar icons for
Eclipse 4.2 using your XWin.exe build running with an without nx.
The titlebar icon does NOT appear when running Eclipse with vanilla X.
The taskbar icon also uses full colors; I do not know if it's a
different icon or if nx is using some kind of compression.
The second set of images (eclipse-4_2-nx_2 and eclipse-4_2-nonx_2)
indicate the time of crash. When Eclipse starts up is displays a splash
image which initially does not have an icon in its titlebar. Notably, a
window border only appears when running Eclipse with nx. Despite not
having a border, the icon is still relevant because it is the same one
used to display in the taskbar.
The crash occurs when the icon is being loaded onto the splash window.
To reiterate, the window is NOT created with this icon. It is loaded
sometime later while Eclipse is initializing.

Perhaps it has to do with the icon being applied after the window has
already been created?

It looked to me like the crash was occurring at line 264 of
icon_convert.c; a memcpy to DIB_pixels which I believe was
uninitialized. Regardless, the memcpy is one without verifying
DIB_pixels or checking the return value of CreateBitmap.
This is what I has planned to look into.. if I ever get XWin.exe to compile.
(I can't seem to send images to the mailing list, so here they are)
These images illustrate the small titlebar icon and its accompanying
taskbar icon:

http://codespunk.com/files/upload/eclipse-4_2-nx.png
These images show the splash image and the visible border when using nx:

Ah. I was hoping you could use xprop to examine the _NET_WM_ICON property of
the window, but if it's a transient state that may not be practical.
I would guess that the difference in appearance between the nx and non-nx
cases is due to nx not transporting some window appearance hints.

I did a bit more testing and managed to craft some malformed _NET_WM_ICON
properties which could crash the multiwindow mode WM in different ways (small
test case attached), so I've added another patch to do more validation of
_NET_WM_ICON data before it is used.
