The code:
-------------------------------------------
typedef char(arr_type)[10];
typedef char(&arr_ref)[10];
arr_ref fn()
{
static arr_type a = {1,2,3,4};
return arr_ref(a);
//return a;
}
-------------------------------------------
Fails to compile on Mingw GCC-3.4.0 with diagnostics:
-------------------------------------------
bug.cxx: In function `char (& fn())[10]':
bug.cxx:7: error: conversion to non-const reference type `char (&)[10]' from
rvalue of type `char*'
bug.cxx:7: error: invalid initialization of non-const reference of type 'char
(&)[10]' from a temporary of type 'char*'
-------------------------------------------
However if replace "return arr_ref(a);" with "return a;" it compiles
