therefore seems an hard to reproduce long-standing problem, after all... 
You can try whether backporting this patch from mainline helps:

2006-03-12  Howard Hinnant  <hhinnant@apple.com>

    * testsuite/27_io/basic_filebuf/underflow/char/10097.cc:
    Fix race condition.
    * testsuite/27_io/objects/char/9661-1.cc: Likewise.
    * testsuite/27_io/objects/wchar_t/9661-1.cc: Likewise.

(not sure if it qualifies for the branch...)

Paolo.
