[ast-developers] Short int array in an user-defined type crashes ast-ksh.2013-07-27 ...

[Roland Mainz]

Hi!

----

The following one-liner crashes ast-ksh.2013-07-27 on SuSE
12.3/AMD64/64bit when I use an array of short integers:
-- snip --
$ ksh -c 'typeset -T x_t=( typeset -s -i i=( 5 6 7 ) ); x_t t ; print
$(( t.i[1]=0xFFFFFFFFFFFE , t.i[1] )) ; true'
-- snip --

Stack trace looks like this:
