Not a bug per se, but a known annoyance to many. Try instead:
sysuse auto, clear
reg price mpg weight
estimates store a
clear
estimates restore a
test mpg
test _b[mpg]=0
*similar when referring to names in e(b) that do not correspond to actual vars:
sysuse auto
svyset [pw=weight]
svy:tab rep78
test _b[p21]=.1
