Comment (by petke@…):

 I noticed the same bug. CoInitializeSecurity returns  RPC_E_TOO_LATE the
 second time it is called. Isn't it an error for CoInitializeSecurity to be
 called more than once for a process? I'll try and revert the
 get_last_bootup_time to the old version.

 Here is the message I sent to boost-users_at_[hidden] in case you need
 more info:

 I think I have found a bug in the boost interprocess library. I would be
 thankful for any workaround.

 I am maintaining some code that was upgraded to use boost_1_45_0 running
 on windows7.

 We have some dll that creates a file for sharing:

 C:\ProgramData/boost_interprocess/20110321233336.335895/share_memory_segment_somenameengine_0

 The dll launches a exe and shares some memory with it. However this exe
 tries to read the shared memory at location:

 C:\ProgramData/boost_interprocess//share_memory_segment_somenameengine_0

 The folder name "20110321233336.335895" is missing in that path name.

 Debugging this is seems to be because the boost library tries to get the
 windows system boot time by calling
 boost::interprocess::winapi::get_last_bootup_time.. which fails for some
 reason. The weird thing is that the exe (indirectly) calls this twice, and
 the first time it works but not the second time. (The dll also calls it
 twice but that works just fine.)

 In get_wmi_class_attribute the time this if statement evaulates to true,
 next time it does not:
         if( 0 == CoInitializeSecurity( 0, -1, 0, 0,
 RPC_C_AUTHN_LEVEL_PKT_IG, RPC_C_IMP_LEVEL_IMPERSONATE_IG, 0, EOAC_NONE_IG,
 0 ) )

 Here is the call stack for context:

 First time work fine CoInitializeSecurity works..
