The following quote comes from Mani Varadarajan, core developer at BE.

"Rule: Don't declare member variables of classes static, if the
member variable is of a nonfundamental type."

Greetinx earthlings,

When compiling the following code using Solaris SC4.0 I get the following
output:

123
1
123

Not what you would expect.....

#include <iostream.h>

struct t_bug {
int a;
int b;
int c;

class Buggy
{
public:
void bugIt(int b = 1) { struct t_bug bug = { 1, b, 3 };
cout << bug.b << endl ;
}
void bugItAgain(int b);

void Buggy::bugItAgain( int b = 1 )
{
struct t_bug bug = { 1, b, 3 };
cout << bug.b << endl ;

void bugIt(int b = 1)
{
struct t_bug bug = { 1, b, 3 };
cout << bug.b << endl;

int main (void)
{
Buggy b;
bugIt( 123 );
b.bugIt( 123 );
b.bugItAgain( 123 );
return 0;

Wha'ya think?
