--- Comment #2 from Joseph C. Sible <josephcsible at gmail dot com> ---
I can reproduce it on godbolt ("Program returned: 139"):
https://godbolt.org/z/c7eYzx
Here's the assembly output:
main:
movslq b(%rip), %rax
cmpq 0, %rax
cmpq $0, d(%rip)
movl $0, %eax
ret
c:
.quad 1
d:
.quad 1
b:
.long 1
The problem is that "cmpq 0, %rax" tries to read memory at address 0.
