It turns out that the fix was only partial.  With the fix, I have finally been
able to reproduce the crash with two files.

$ cat >a.cxx
#include <iostream>

class Hello
{
public:
   Hello () {}
  ~Hello () {}
  void act (void);
};

void Hello::act (void)
{
  std::cout << "Hello, world!" << std::endl;
}

$ cat >aa.cxx
#include <ext/bitmap_allocator.h>
class Hello
{
public:
  Hello ();
  ~Hello ();
  void act (void);
};

static void __attribute__ (( constructor )) PWLIB_StaticLoader() {
  __gnu_cxx::bitmap_allocator<Hello> allocator;
  Hello* salut = allocator._M_allocate_single_object ();
  salut->act ();
}

int main (void)
{
  return 0;
}

$ g++ aa.cxx a.cxx
$ ./a.out
Segmentation fault

By chance, I discovered that the order of compilation is important:
$ g++ a.cxx aa.cxx
$ ./a.out
Hello, world!

Cheers,
Eugen
