math mode underbar broken ?

math mode underbar broken ?

[Steffen Wolfrum]

Hi,

I just came across this discrepancy:

\starttext

\startformula
  H_1 + H_A = f(\underbar{α})
\stopformula

$  H_1 + H_A = f(\underbar{α}) $

\startformula
  H_1 + H_A = f(\overbar{α})
\stopformula

$  H_1 + H_A = f(\overbar{α}) $


\stoptext



Is this known or is under/overbar broken in display math mode?

IIRC, this has been broken for a while.

it's a side effect of a buglet in luatex, the next beta works around it 
for pre 0.70 versions
