I think that's a bug too

------- Comment #10 from dougsemler at gmail dot com  2010-05-10 17:18 -------
Well, is it really invalid code with -std=c++0x?

The virutal destructor seems to be causing the issue.

With gcc 4.4.3 (after changing virtual ~base() to virtual void func()):

$ g++ gcc_bug.cc 
gcc_bug.cc: In function ‘int main()’:
gcc_bug.cc:9: warning: extended initializer lists only available with
-std=c++0x or -std=gnu++0x

$ g++ gcc_bug.cc  -std=c++0x
$


So you can see that g++ sees this as valid code.

The testcase is invalid; 5.17 doesn't allow assignment to an array from an
initializer list (although I'm not sure why not).  But certainly we should give
an error rather than crash.

Reduced test case:

# 1 "gcc_bug2.cc"
# 1 "<built-in>"
# 1 "<command-line>"
# 1 "gcc_bug2.cc"
struct base
{
   virtual ~base() { }
};

int main()
{
 base ptr_array[1];
 ptr_array = { base() };
}

If it's a segmentation fault, isn't a library issue, that for sure.
