>Description:
I've tested this with sh from -current and emacs 19.34.1
If you run sh -c 'emacs -nw' and then press control-g (at any stage
in editing) it appears that sh crashes, leaving emacs looping on
an error trying to access it's tty.

tcsh or bash -c 'emacs -nw' does not exibit this problem.

ktrace sh -c 'emacs -nw' gives:
[...]
 22003 sh       NAMI  "/usr/local/bin/emacs"
 22003 sh       RET   stat 0
 22003 sh       CALL  break(0x55ffc)
 22003 sh       RET   break 0
 22003 sh       CALL  break(0x56ffc)
 22003 sh       RET   break 0
 22003 sh       CALL  fork
 22003 sh       RET   fork 22004/0x55f4
 22003 sh       CALL  getpgrp
 22003 sh       RET   getpgrp 22003/0x55f3
 22003 sh       CALL  wait4(0xffffffff,0xefbfd5d4,0x2,0)
 22003 sh       PSIG  SIGINT SIG_DFL

Messy signal handling somewhere ?

sh -c 'emacs -nw'
