Extended Description

Created an attachment (id=561)
Source code to reproduce behaviour
Using rev16340 of sac2c, compilation of the following program aborts reporting an error about inferred types being out of bounds:
---
module badbounds;
use Structures : all;
use Numerical : all;
export {badbounds};
complex[.,.,.,.] badbounds( complex[.,.,.] input)
{
 result =
   with
     {
       ( [0,0,0,0] <= [i,j,k,l] < [1,1,1,1]) : input[0,0,0];
     } : genarray( [1,1,1,1], toc(0,0));
 return( result);
}
---
The (clipped) compiler output reads:
---
