I've filed just the same bug against Debian package of ash. This is the
answer I got from Herbert Xu, also an upstream of what's called "dash",
Debian fork of ash shell (it has just the same behaviour as FreeBSD's
ash):

You're mistaken. SUSv3 only requires constant arithmetic. Variables
must be expanded before reaching arithmetic expansion.
Read C.2.6.4 for a detailed explanation.

Please use bash/ksh instead.

truth?
