Just avoid it entirely and do it in Mata:

mata:mata clear
mata:
void function mm_svmat2(string scalar mat, string scalar vlist)
{
	m = st_matrix(mat)
	vv = tokens(vlist)
	st_view(X=., 1::rows(m), vv)
	X[. , .] = m
}
end

program drop _all
prog svmat2
syntax anything [,stub(string)]
local vn = cond("`stub'" == "", "var", "`stub'")
scalar nc = colsof(`anything')
forv i=1/`=nc' {
	local vname "`vn'`i'"
	qui gen double `vname' = .
	local vl "`vl' `vname'"
}
mata: mm_svmat2("`anything'","`vl'")
end

webuse auto, clear
qui corr price mpg headroom trunk weight length
mat corr=r(C)

svmat2 corr
svmat2 corr, stub(sergiy)
