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

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

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;
}
