5392	"Message queue temporary dir named ""Select LastBootUpTime from Win32_OperatingSystem"" (on win XP)"	wsx22@…	Ion Gaztañaga	"

There is still problem with message queue temp directory related to bug https://svn.boost.org/trac/boost/ticket/4010

I'm using boost interprocess message queue on Windows XP SP3 32bit, and boost 1_46_1

In first application i'm executing function

{{{
mq = new boost::interprocess::message_queue(
		boost::interprocess::create_only 
		,mqName->c_str()
		,10
		,sizeof(MqMessageStruct)
	);
}}}

then boost creates temp directory

C:\Documents and Settings\All Users\Application Data\boost_interprocess\20110327091835.364787\

this is OK.
In second application I try to create message_queue object by execute constructor

{{{
boost::interprocess::message_queue mq(
		boost::interprocess::open_only
		,mqName->c_str()
	);
}}}

boost creates temp directory named:

{{{
C:\Documents and Settings\All Users\Application Data\boost_interprocess\Select LastBootUpTime from Win32_OperatingSystem\
}}}

and throws exception. Existing message queue can't be open and can't work.
In boost 1_44 this code was working good (except issue described in ticket 4010)

I've watching source code and I think that problem is somewhere in file 
boost_1_46_1\boost\interprocess\detail\win32_api.hpp
in function 
inline bool get_wmi_class_attribute( std::wstring& strValue, const wchar_t *wmi_class, const wchar_t *wmi_class_var)
between lines 1525 and 1558.
Maybe  pEnumObject Object in line 1547 is empty.

Another issue is that in file
\boost_1_46_1\boost\interprocess\detail\tmp_dir_helpers.hpp 
in function 
inline void get_bootstamp(std::string &s, bool add = false)
(line 38) there is no check for result returned from
winapi::get_last_bootup_time(bootstamp);
(line 41)
