gcc exception handle

[王 刚伟 <gwwang10@xxxxxxxxxxx>]

Hi,

Here is My test function :

class A
{
public:
private:
char string[SIZE];
};

void test1(void)
{
   A obj;

   try 
   {
      throw obj; 
   }
   catch (A &e)
   {
      printf("exception ! \n");
   }
}

when SIZE <= 68,"__cxa_allocate_exception" allocates space for the 
exception successfully,after "__cxa_throw" is called,"__cxa_begin_catch" is 
called,and the statement "printf..." in the catch block can be executed.
when SIZE > 68, ,"__cxa_allocate_exception" also allocates space for the 
exception successfully,but after "__cxz_throw" is called,"__cxa_end_catch" 
is called,and the program crashed.

Did the error occur in compilation period or link period?
How can I make the compiler support SIZE <= the size of Task Space?

Any suggestions?

thank you!
