g++ 1.36.1 bug

I ran into a bug related to the "new" operation:
=============================================================================
#include "stdio.h"
class Foo {
private:
char* name;
public:
Foo(char* s);
check(int, Foo* f, int);
};
Foo::Foo(char* s) {
name = s;
}
Foo::check(int a, Foo* f, int b) {
printf("%d %d %d\n", a, (int)f, b);
}
main() {
Foo a("test");
a.check(1, new Foo("crash"), 2);
}
-------------------------------------------------------------------------
[uw-larry - 120] % g++ main.c
[uw-larry - 121] % a.out
1 148520 148520
=============================================================================
Apparently the stack gets clobbered by the "new" operation. If I change
the main program as show below, things work fine
=============================================================================
main() {
Foo a("test");
Foo* b = new Foo("crash");
a.check(1, b, 2);
}
-------------------------------------------------------------------------
[uw-larry - 124] % g++ other.c
[uw-larry - 125] % a.out
1 148520 2
=============================================================================
g++ version 1.36.1 (based on GCC 1.36)
Sun3, os3
Any help would be **GREATLY** appreciated...
