State-Changed-Why:
This is almost certainly a gdb bug. Try running insight's and gdb's varobj testsuites to see if they exhibit the problem. If not, you're going to have to supply a (hopefully simple) testcase to reproduce this. FWIW, technically it is gdb that is quitting (because of the internal error). That's what gdb does.

I get this with Insight 6.6, but have no corresponding problem when I
use gdb, even the one that has been built in the insight bin directory.
Here's a test program (compiled with the command line g++ -g itest.C -o
itest):
int main () {
char *p =3D (char*)0;
return 0;
}
To trigger the problem, break on the return statement, and then either:
a. Select the expression '*p' in the second line.
b. Float the pointer over the highlighted expression. So long as it
is over the '*', it shows 'p=3D(char*)0', but as soon as it touches the
'p', the assertion fires.
Or try to set *p as a watch expression.
In gdb, the equivalent actions, 'p *p' and 'watch *p', simply elicit
'Cannot access memory at address 0x0'.
The system:
