If a Vtk/Tcl program dumps core, use:

  $ gdb `which vtk` core  # note REVERSE quotes

from the directory in which the core is located.

Then type "where" to get a stack dump.
Possibly "list" to see at which line in the source code the fault
happened (works only when the code where the crash occured has been
compiled with debugging symbols).

Of course, you still have a way to go to get back to the script line
that produced the core. If you want to debug a script, consider the
tcl_traceExec and tcl_traceCompile variables (set them both to 1)
or get a Tcl debugger.
