[Bug c++/61282] vectorization causes segfaults in a compiled program during access to an int-casted char[] after bool in a struct
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=61282 --- Comment #3 from V. Pimenov --- Because gcc should not use SIMD instructions for unaligned arrays.

Your program has undefined behavior in it, gcc assumes undefined behavior does not happen in a valid program.

[Bug target/59904] [ARM] tls-reload-1.c fails
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=59904
--- Comment #7 from wangzheyu ---
After a close analysis of your elf, it will fail due to bad code in first call
to function checktls23. The corresponding C code is:
if (!y || *y++ != &tls23 || *y++ != &tls23_array[3]) return 0;
The code to get address of variable tls23 is wrongly fixed up. Here is the
assembly code with analysis embedded:
checktls23:
push{r4, lr}
mov r3, r0
sub r2, r0, #0
beq .L136
ldr r2, .L140 << get offset of variable tls23
ldr r1, [r0]
bl __aeabi_read_tp @ load_tp_soft << get thread point and save it
to r0
add r0, r0, r2 << thread point plus offset equals address of
variable tls23
mov r2, #0
cmp r1, r0
bne .L136
ldr r4, .L140+4
bl __aeabi_read_tp @ load_tp_soft
ldr r1, [r3, #4]
add r0, r0, r4
cmp r1, r0
bne .L136
add r3, r3, #8
mov r2, r3
.L136:
mov r0, r2
@ sp needed
pop {r4, pc}
.L141:
.align 2
.L140:
.word .LANCHOR2(tpoff)+124 << offset of tls23 is correctly
generated. but never get correctly fixed up.
.word .LANCHOR3(tpoff)+12
So my advice is to use a newer version of binutils to test it again.
