Basically what I am trying to say is there is a lot of analysis needed to
determine if the lifetime of object does not end during a call to a virtual
function.

--- Comment #1 from Ryan Johnson ---
It appears that multiple calls to different virtual functions of the same
object are not optimized, either (each performs the same load-load-jump
operation).

I can confirm patch fixes my Qt build, ie. not just bug.cpp.

--- Comment #2 from Andrew Pinski ---
So to fix this in reality is to change how POINTER_PLUS_EXPR takes an unsigned
integer to be a signed integer. But this will take many extra issues and need
to be done though out the compiler.
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=77899
--- Comment #1 from Andrew Pinski ---
This is the complex part because size_type is unsigned so the range converting
from signed [-127, 128] to unsigned is ~[128, 18446744073709551487]
