Hi Sebastian,

\starttext
\startformula
S=\left(\matrix{
\sigma_x & \tau_{xy} & \tau_{xz} \cr
\tau_{yx} & \sigma_y & \tau_{yz} \cr
\tau_{zx} & \tau_{zy} & \sigma_z \cr
}\right)_{xyz}
\stopformula
\stoptext

My guess is that the different results may be related to the OS.

I’m on Linux 32bit using luatex-0.90.0. As far as I know, Windows is
provided with luatex-0.95.0.

This might be the cause of the different results. But it is only my
guess. If this is the cause, you may have found a bug in luatex-0.95.0.

I hope it helps,

Pablo
