Sorry, I still screw this up too often since the default/button order
has changed in Thunderbird.
If your invariant is called from the GC during finalization, it might
have to do with the debugger executing code to show structs or ranges.
Are you using the visualizer methods __debugOverView, __debugExpanded,
etc.? Are ranges displayed in your Auto/Local/Watch windows?
No, I don't.
You can try to disable implicit code execution by the debugger in
Tools->Options->Debugging->Mago by unchecking options "Call
struct/class..." and "Call range methods".
Yes, the option `Call range methods` causes the problem! Is that still
experimental in VisualD 1.2.0? Please do not enable it by default then.
It's a bit dangerous because executing code automatically can mutate
your program state.
The default has been changed quite some time ago
(https://github.com/rainers/mago/commit/8ce1bb37818ea38e88ec8ecf2439383b592fca46),
so you probably picked up the enabled state as an early adopter.
