EXC_BAD_ACCESS writing to cout with PFE precompiled headers


I'm running the Apple's release of GCC:

g++ -v
Reading specs from /usr/libexec/gcc/darwin/ppc/3.1/specs
Thread model: posix
Apple Computer, Inc. GCC version 1161, based on gcc version 3.1 20020420
(prerelease)

and am having trouble with precompiled headers. I am stumped. It previously
worked on 1/2 of my Mac's running Jaguar, but today it's down to 0/2. The
precompiled headers seem to work fine unless I try to precompile
<iostream.h> and write to cout. The precompiled header is (pch.cpp):

#include <iostream.h>

The test program is (test.cpp):

#include <iostream.h>

int main(void)
{
        cout << "hello" << endl;
        return 0;
}

I build the precompiled header with:

c++ --dump-pch foo -c pch.cpp

and build the test program with:

c++ --load-pch foo test.cpp -o test

when I run the executable, it dies with:

Program received signal EXC_BAD_ACCESS, Could not access memory.
0x0000a1d4 in std::ostream::sentry::sentry(std::ostream&) ()
(gdb) where
#0  0x0000a1d4 in std::ostream::sentry::sentry(std::ostream&) ()
#1  0x0000a424 in std::basic_ostream<char, std::char_traits<char> >&
std::operator<< <std::char_traits<char> >(std::basic_ostream<char,
std::char_traits<char> >&, char const*) ()
#2  0x00001d98 in main () at test.cpp:5
#3  0x00001b14 in _start (argc=1, argv=0xbffff83c, envp=0xbffff844) at
/SourceCache/Csu/Csu-45/crt.c:267
#4  0x00001994 in start ()

Any clues?

Many thanks.
