I'm having troubles.
Today XCircuit seg faulted when I was saving a file. It lost _all_ the
original data and wrote a empty file in it's place.
I'm not sure which version I was using. It was built from CVS.
So today I checked out the source from CVS (it reports revison
3.6.83), built it with tcl-enable.
This time I made a backup copy of my file first, then I opened the
file, and finally saved it with a new file name.
seg fault.
empty file (the new one, not the one I opened)
This is on Debian Etch (stable) i386.
The console I ran it from has no output except reporting the
segmentation fault.
Below is the report from the debugger.
