Re: [Boost-users] [iostreams] Hang when constructing an xml_iarchive with non-existent source

I wonder if this is bzip-related.  If you comment out the bzip line, the 
program throws an exception:

Exception thrown:

    First-chance exception at 0x7c59bbf3 in IostreamsTest.exe: Microsoft 
C++ exception: boost::archive::xml_archive_exception @ 0x0012fad0.

Breaks at:

    this->restore()

in:

    ios_flags_saver::~ios_flags_saver()

Call stack:

     KERNEL32.DLL!7c59bbf3()    
     KERNEL32.DLL!7c59bbf3()
