Package: gcc-5
Version: 5.3.1-4
Severity: normal
Dear Maintainer,
echo "typedef const int Arr[];int foo (Arr a){return a[0];}" | gcc-5 -c -xc -
leads to
<stdin>: In function ‘foo’:
<stdin>:1:1: error: invalid use of array with unspecified bounds
<stdin>:1:48: warning: return makes integer from pointer without a cast [-Wint-
conversion]
No error and no warning with gcc-4.9
