[Boost-users] [test] Linking against boost_unit_test_framework causes double-deletion in std::ostringstream

Just curious if anyone else has seen this or anything like it? Platform 
is Mac OS X 10.6.1, gcc 4.2.1, boost 1.40.0 installed from MacPorts, 
compiling 64-bit (default).

Here's my test code:

#include <sstream>

int main()
{
    std::ostringstream str;
    str << "Help Me!";

    return 0;
}

Here's what I'm doing:

% g++ -o streamtest_bad -ggdb -L/opt/local/lib 
-lboost_unit_test_framework-mt-d streamtest.cpp
% ./streamtest_bad
streamtest_bad(63554) malloc: *** error for object 0x7fff7008a500: 
pointer being freed was not allocated
*** set a breakpoint in malloc_error_break to debug
zsh: abort      ./streamtest_bad
%

Works fine against other boost libraries, eg system:

% g++ -o streamtest_good -ggdb -L/opt/local/lib -lboost_system-mt-d 
streamtest.cpp
% ./streamtest_good
%

Note that this seems to be a separate problem to that reported in 
ticket 3432 (https://svn.boost.org/trac/boost/ticket/3432). At least, I 
have verified that the framework::clear() function isn't being called 
in the above code, which does tend to point the finger at a different 
part of the library.

The backtrace is not particularly enlightening, but posted here for the 
sake of completeness:
