PR33749 - Wrong evaluation of expressions in lhs of assignment statements

[Paul Richard Thomas]

Dear All,

This is the offender:
      ASSIGN MAIN__:p(__convert_i4_i8[[((MAIN__:p(FULL)))]]) (/ 1 , 2 , 3 , 4 /)

The conversion comes through and triggers an unconditional production of a temp.

I now feel confident about submitting the patch - it's on its way in a few days.

Cheers
