[Qt-interest] QScriptEngine: "Could not allocate register file: 12"

[Malyushytsky, Alex]

std::bad_alloc exception is thrown in C++ when object can't be allocated?.
Application is terminated when you don't catch exceptions.
This is C++ standard behavior.

It seems that something is wrong with the QScriptEngine the following code
produces a crash with the error:

  "Could not allocate register file: 12"

     int i = 0;
     while(i<600)
     {
         QScriptEngine  *en = new QScriptEngine();
         i++;
     }

On the other way I tryed the same allocating QStrings. It takes much more
iterations to produce a crash and it cosumes nearly all of my RAM before it
crashes with the error:

"terminate called after throwing an instance of 'std::bad_alloc'
   what():  std::bad_alloc"

     int i = 0;
     while(i<40000000)
     {
         QString *str = new
QString("fddddddddffffffffffffffffffffffffffffffffffffffffff");
         i++;
     }


Can someone confirm and explain that behaviaor?

Greetings
Pedro Santos
