--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
I don't know if this is a bug really.
The statement on line 9 (`e = b + 1;`) gets removed and therefor there was no
undefined behavior that happens at all.


Either DSE or CDDCE does the removal (depending on if you use -Og or -O1):

  Deleted trivially dead stmt: [/app/example.cpp:9:7] e_9 = (long int) _2;

  Deleted trivially dead stmt: [/app/example.cpp:9:11] _2 = .UBSAN_CHECK_ADD
(2147483647, 1);
