As Charles L. Werner wrote in a different thread even after downgrading
X again to 6.8.2 the problem remains. :(

And the "The NTVDM CPU has encountered an illegal instruction" or similar
popup has nothing to do with symbolic links. Try this:

$ cd /usr/grace/bin/

$ strace ./xmgrace.exe

and you'll get a popup.

I tried gdb, but:

$ gdb ./xmgrace.exe
GNU gdb 6.5.50.20060706-cvs (cygwin-special)
(snip)
This GDB was configured as "i686-pc-cygwin"...(no debugging symbols found)

(gdb) run
Starting program: /usr/grace/bin/xmgrace.exe

Program received signal SIGSEGV, Segmentation fault.
Error: dll starting at 0x771000 not found.

Program received signal SIGSEGV, Segmentation fault.
---Type <return> to continue, or q <return> to quit---

Program received signal SIGSEGV, Segmentation fault.

Program exited with code 030000000005.
You can't do that without a process to debug.


that doesn't help much either. Over the weekend I'll build a xmgrace
version with debug information. Maybe that helps.
