https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D235783 --- Comment #10 from Andriy Gapon <avg@FreeBSD.org> --- (In reply to Jurij Kovacic from comment #9) Okay, compare the value of r13 (and this is the original db pointer) to the value in rcx. They differ by a single bit: (gdb) p/x 0xfffff8028de9cae0 ^ 0xffff78028de9cae0 $1 =3D 0x800000000000 The values in rbx and rax are derived from the value in rcx. And the crash happens when accessing the address stored in rax. This was a long way to say that most likely you got a single bit flip on the hardware level. I assume that the RAM is not ECC. --=20 You are receiving this mail because: You are the assignee for the bug.=
