So I set stack-protector-all as "other C++ flags" and got
_stack_chk_fail
So this means the C++ constructor is corupting the stack?

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.
