Ah, now I see. Sorry, I dismissed your remark too soon
yesterday. I should have tried and looked a bit better.

In the process of looking into it now, I did find some
unreliability in te i386 executable, which possibly stems
from the same bug as your crash.

You are right, this behaviour is unexpected. I am not
sure if it can be fixed in a meaningful manner, I will
look into that (Whatever else happens, I cannot go back to
the eTeX bidi subsystem, because it simply is not powerful

Meanwhile, this works as expected:

   \hbox dir TLT{#}&\hbox dir TRT{#}\cr
   This and&that\cr}

Best wishes,
