https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D230144 meowthink@googlemail.com changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |meowthink@googlemail.com --- Comment #14 from meowthink@googlemail.com --- Same issue here. stable/11 r338649 on a Ryzen 2400G. $ truss -f /compat/linux/usr/bin/bash 4163: linux_brk(0x0) =3D 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=3DSEGV_MAPERR trapno=3D12 addr=3D0x7fffffff= f508 4163: process killed, signal =3D 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. --=20 You are receiving this mail because: You are the assignee for the bug.=
