--YZ5djTAD1cGYuMQK Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable I've recently updated a box from 8-stable to 9-stable/amd64 (r237995), compiled with gcc, and now sh(1) exits if I change the window size (ssh'ing to the target system within an xterm). I don't recall ever seeing this sort of behaviour before and am still trying to track down the relevant code path. ktrace output looks like: 1766 sh GIO fd 2 wrote 2 bytes "# " 1766 sh RET write 2 1766 sh CALL ioctl(0,TIOCGETA,0x801020364) 1766 sh RET ioctl 0 1766 sh CALL ioctl(0,TIOCSETAW,0x801020338) 1766 sh RET ioctl 0 1766 sh CALL read(0,0x7fffffffda8f,0x1) 1766 sh RET read -1 errno 4 Interrupted system call 1766 sh PSIG SIGWINCH caught handler=3D0x417d10 mask=3D0x0 code=3D= 0x10006 1766 sh CALL sigreturn(0x7fffffffd600) 1766 sh RET sigreturn JUSTRETURN 1766 sh CALL ioctl(0,TIOCSETAW,0x80102030c) 1766 sh RET ioctl 0 1766 sh CALL setpgid(0,0x6e6) 1766 sh RET setpgid -1 errno 1 Operation not permitted 1766 sh CALL ioctl(0xa,TIOCSPGRP,0x7fffffffda74) 1766 sh RET ioctl 0 1766 sh CALL close(0xa) 1766 sh RET close 0 1766 sh CALL exit(0) Does this ring any bells with anyone? --=20 Peter Jeremy --YZ5djTAD1cGYuMQK Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.19 (FreeBSD) iEYEARECAAYFAk/0FPQACgkQ/opHv/APuIcIugCgjPcmQLilDqFoPHnJaO9jMbg0 nSsAoLWATPwAJ6wSxNXT3d4Tm0SecQPa =EHtx -----END PGP SIGNATURE----- --YZ5djTAD1cGYuMQK--
