[Bug c/17076] New: ICE on variable size array initialization in debug mode in C++

["kunegis at cs dot tu-berlin dot de" <gcc-bugzilla at gcc dot gnu dot org>]

An internal compiler error in G++ version 3.4.1 in debug mode using variable
size arrays.  The size of the array is taken from the member of a struct that is
returned by a function.  The source is in preprocessed C++.  

----------BEGIN FILE bug.ii---------
struct Integer
{
	int x;
};

Integer f()
{
	return (Integer){45};
}

int main()
{
	int numbers[f().x];
	return 0;
}
------END FILE bug.ii-----------

Sample session:

$ g++ bug.ii
$ g++ -g bug.ii
bug.ii: In function `int main()':
bug.ii:15: internal compiler error: in loc_descriptor_from_tree, at dwarf2out.c:8863
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
$ gcc --version
gcc (GCC) 3.4.1

Notes:
-When compiled as the file "bug.i" using "gcc", no ICE happens and the compiler
reports an error.
-I don't know whether the code is correct.
-The ICE could not be reproduced in gcc 3.3.3 on i686-suse-linux.
