Bug#890350: splint: Internal Bug constraintGeneration.c: llassert failed: exprNode_isDefined(t1) [errno: 25]

[Shea Newton <sheanewt@gmail.com>]

Package: splint
Version: 3.1.2.dfsg1-2
Severity: normal

Dear Maintainer,

I've run into some C syntax that causes the `splint` program to report an "Internal Bug".

Here is the exact command and its output.

```
$ splint constant.c  
Splint 3.1.2 --- 03 May 2009 

constraintGeneration.c:1381: at source point 
constant.c:9:2: *** Internal Bug at constraintGeneration.c:1381: 
              llassert failed: exprNode_isDefined(t1) [errno: 25] 
    *** Please report bug to submit@bugs.debian.org (via reportbug) *** 
      (attempting to continue, results may be incorrect) 

Finished checking --- no warnings 
  1 internal bugs reported

```

And here is the reduced program that causes this report.

```
/*
 * constant.c
 */

int main(void)
{
    const int * const const_val = &(int){ 1234 };
    return *const_val;
}
```

Thank you.
