Hi,

GCC problems solved. Many thanks for your help.

Test app shows answers:

Mandriva 2009.1. 2gb RAM 4gb swap. overcommit_ratio=50 (presumably should 
die at 300gb + but doesnt).

/proc/sys/vm/overcommit_memory is reset to 0 on boot so man malloc solution 
of
cat 2 > /proc/sys/vm/overcommit_memory doesnt work (probably would if placed 
in some boot script
but thats a Mandriva issue).

#include <string.h>
#include <iostream>

using namespace std;

int main()
{
 //long long llSize = 1000000*1024*1024LL;     // 1,048,576,000,000 bytes. 
Succeeds!
 long long llSize = 0xFFFFFFFFFFFFFFFFLL; // This generates an exception

 try
 {
  char * pMem = new char[llSize];

  cout << "new worked" << endl;

  memset(pMem, 1, llSize); // Seems to work

  pMem[llSize - 1] = 2;      // Seems to work

  if(pMem)
    delete pMem;                // No problems
 }
catch(...) // This works on gcc 4.3.2 (needs #include <new> if 
std::bad_alloc caught)
 {
  cout << "catch(...)" << endl;
  return 1;
 }

 return 0;
}

Once again, many thanks for your help.
