Cause insight to crash with SEGV
Insight version:
GNU gdb 2003-01-09-cvs
gcc version:
gcc version 2.95.3-5 (cygwin special)
Compiled with -g option.

When debugging main.cc, moving the mouse over the statement:
 thisRoute->analyzeZD();
causes insight to crash with a SEGV.

Set a break point on line 57. Run and then place the mouse on line 57.

The following is the error (captured by running insight within gdb):
Program received signal SIGSEGV, Segmentation fault.
0x6108d57f in _libtk80_a_iname ()
