Modified Files:
src/bin/sh: eval.c
Log Message:
Use a volative local shadow of a field in an (on-stack) non-volatile struct
that is to be referenced after a return from setjmp() via longjmp().
This doesn't ever seem to have caused a problem, but I think using
volative vars is required here.
For reasons I never bothered to discover, even though this change
certainly requires a store into stack memory which wasn't required
before, earlier measurements showed the shell getting (slightly) smaller
with this change in place.
