Target? Named locales are supported *only* on GNU/Linux systems.

I am learning the QT package, and for example its QString provides a
toStdString() function that returns

The bug reports you are mentioning combined with 35353
(http://gcc.gnu.org/bugzilla/show_bug.cgi?id=35353), means that the locales
implementation of GCC is a mess.
I think the proper solution is to fix the locale

May you be more specific and tell what exactly is invalid? That is what is the
error in the source code.

The bug can easily be in the library.

To be more precise: I believe the bug is in the library.

I am sorry but you are not right/specific.
At first there is no struct in the code, only class. Second, the copy
constructor does not copy the passed argument, it ignores it. But it
initialises its data member the same
--- Comment #11 from ivranos at freemail dot gr 2008-10-03 08:48 ---
I posted the code to c.l.c++ with the subject Segmentation fault. If noone
finds any bug, I will reopen the bug here.

The prurpose of the code is to benchmark the sorting of a vector and of a list
with complex objects as their elements (SomeClass).
SomeClass itself doesn't make any other sense, its purpose is to be complex.
I think

So, if there isn't any source code bug at my side, and it is a compiler bug,
you mean the maintainers don't care to fix it?

I managed to replicate the bug in simple code:
#include iostream
#include ctime
#include cstdlib
#include vector
int main()
{
using namespace std;
vectorint intVector(1000*1000);
srand(time(0

The bug occurs in this simpler code too:
#include iostream
#include ctime
#include cstdlib
#include vector
#include limits
int main()
{
using namespace std;
vectorint intVector(1000*1000);
srand(time

sync_with_stdio (false) doesn't work. Actually it crashes the code.

difference between the C++ working code and the C++ non-working code

I am sorry for insisting on this, but I think there is an issue, and I want the
best for GCC. So please have a look at the messages of this link:
