           Summary: memory leaks with 'class X { std::list<X> t; };'
           Product: gcc
           Version: 3.3.1
            Status: UNCONFIRMED
          Severity: critical
          Priority: P1
         Component: c++
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: ant_diaz at teleline dot es
                CC: gcc-bugs at gcc dot gnu dot org
 GCC build triplet: i586-linux-gnu
  GCC host triplet: i586-linux-gnu
GCC target triplet: i586-linux-gnu

The following example compiles without problem with g++ 3.3.1 (glibc 2.3.1). But
the produced executable runs out of memory in no time.

  g++ -Wall -W -o test main.cc
  ./test
  Out of memory

  g++ -v
  Reading specs from /usr/local/lib/gcc-lib/i586-pc-linux-gnu/3.3.1/specs
  Configured with: ../gcc-3.3.1/configure --enable-languages=c,c++ --disable-nls
  Thread model: posix
  gcc version 3.3.1

Doesn't occur if:
  replacing 'list' with 'vector'
  using g++ 3.2.2 (glibc 2.3.1)
  using egcs 1.1.2 (glibc 2.1)

-------- EXAMPLE BEGINS -------
#include <list>

class X { std::list<X> t; };

void f1() { X x; };

int main()
  {
  while( true ) f1();
  return 0;
  }
------- EXAMPLE ENDS -------

[Bug libstdc++/12487] memory leaks with 'class X { std::list<X> t; };'

------- Additional Comments From pinskia at gcc dot gnu dot org  2003-10-02 01:37 -------
This is fixed on the mainline at least, I do not know if this is fixed on the 3.3 branch though.
But really this is not considered a bug, see <http://gcc.gnu.org/ml/libstdc++/2002-10/
msg00044.html>.
