--- Comment #3 from Xi Ruoyao <xry111 at gcc dot gnu.org> ---
Please try not to create more reports with "not sure if there is UB" esp. this
UB should be obvious, and it's also detectable with -fsanitize=undefined:
t.c:13:7: runtime error: load of address 0x7ffd53183020 with insufficient space
for an object of type 'int'
0x7ffd53183020: note: pointer points here
2a 56 00 00 01 00 00 00 00 00 00 00 00 14 1a ed ca 50 d4 0e 00 00 00 00 00
