Make is stuck in an infinite loop for me.

The lines from subst-config-vals.sh are ...

190 function expand_var ()
191 {
192   eval tmp="\$$1"
193   while echo "$tmp" | grep '\${[A-Za-z_][A-Za-z0-9_]*}' > /dev/null; do
194     eval tmp="$tmp"
195   done
196   eval $1="\"$tmp\""
197 }

Is anyone else seeing this?

Only happens for the default branch and when I clean up everything.

hg status | grep '^? ' | sed "s/^? /rm /g" | /bin/sh
hg purge
