Oh I forgot to do -fstack-protector-all where do I set that?

Try logging the value of self, rather than relying on the debugger
display. The debugger can sometimes be wrong.
Otherwise, make sure the constructor of your C++ class isn't
trashing memory. Sounds like writing past the bounds of a stack
variable.
If you're doing placement new, you might also be messing that up.
You could try compiling with -fstack-protector-all to try to detect
stack smashers closer to where/when they happen.
