Same issue here. stable/11 r338649 on a Ryzen 2400G.

$ truss -f /compat/linux/usr/bin/bash
 4163: linux_brk(0x0)                            = 7221248 (0x6e3000)
pid 4163 comm bash: signal 11 err 4 code 1 type 12 addr 0x7ffffffff508 rsp
0x7fffffffcb10 rip 0x8006ea3c1 <80 3f 00 0f 85 9e 01 00>
 4163: SIGNAL 11 (SIGSEGV) code=SEGV_MAPERR trapno=12 addr=0x7ffffffff508
 4163: process killed, signal = 11 (core dumped)

But 32-bit linux binaries just run fine.

I'm pretty sure this isn't r335702 related, as brk(0) will always return the
old value. Most weird thing here is, this seems not affect Intel CPUs, but I
can't find any differences in code.
