Description :
[bug 7435 from old bts, reported by David Mentré] Hello,
Using this code: === bidim_array.c int a[12][45] = {0, };
//@ assigns a[..][..]; void f(void) { a[1][3] = 42; }
void main(void) { f(); }
The assigns clause triggers an internal error in Jessie.

Additional Information :
Normalization of multi-dimensional array accesses in jessie plugin is not compatible with use of range.
