Error in Cygwin/X 64-bit

Error in Cygwin/X 64-bit

[Girish Joglekar]

I installed cygwin and cygwin/X 64-bit on a Windows 10 laptop. I have
an application that uses Motif and Xt libraries. It runs on Linux and
Windows Vista with cygwin cygwin/X 32-bit. On Windows 10 I get
segmentation fault in cygXm-4.dll in the function XmRenderTableCopy().

Please help. I can send screen dumps of stack. I do not know how to
copy from X term screen and paste into gmail on PC. Email with screen
is not deliverable to cygwin.

Thank you.
Girish

Is this unnamed application available for others to try to reproduce the 
problem?

Xterm copies text selected using the left-mouse button to the clipboard.

Unfortunately I inherited this code which is huge. I do not know how
to create a simple case which will reproduce the behavior. Is there a
way to create the dlls which shed some light on the problem through
gdb?
Thank you.

Here is the stack from gdb/where at the time it crashes.

For source-level debugging of these DLL with gdb, you can get debug 
information for these DLLs by installing the motif-debuginfo and 
libXt-debuginfo packages.
