hi -
The current cvs version of g++ (2.96 20000320 on i686-pc-linux-gnu)
gets an ICE on the following input if -O2 is used:
--------------------------------------------------------------
class AA {};
void fee (const AA&);
class basic_string
{
public:
basic_string(const char*);
~basic_string()
{ fee (this->get_allocator()); }
AA get_allocator();
};
class failure
{
public:
failure(const basic_string& __str);
};
class foo
{
public:
foo(int x)
{
throw failure ("");
}
};
void test05()
{
foo ofs(0);
}
--------------------------------------------------------------
$ ./cc1plus -O2 x.cc
void test05 ()
x.cc:11: Internal compiler error.
x.cc:11: Please submit a full bug report.
x.cc:11: See <URL:http://www.gnu.org/software/gcc/bugs.html> for
x.cc:11: instructions.
Here's where it's crashing:
Program received signal SIGSEGV, Segmentation fault.
