Bug ID: 55129
           Summary: Boost throws c++ exception when creating shared memory
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: advapi32
          Assignee: wine-bugs@winehq.org

simple c++ repro case
boost uses 2 methods to fetch the boot time to build a path for shared memory. 
code path is chosen with a #define
the 2 methods are:
- registry key (default):
    - BootId and optionally additionally HybridBootAnimationTime
    -
https://github.com/boostorg/interprocess/blob/boost-1.82.0/include/boost/int...
    - creates a path like: C:/ProgramData/boost_interprocess/01000000/crash
- Eventlog
    - fetches record for event log start
    -
https://github.com/boostorg/interprocess/blob/boost-1.82.0/include/boost/int...
    - creates a path like: C:/ProgramData/boost_interprocess/1687093260/crash
    - the event log timestamp is always moments after boot on physical and
virtual machines i have access to, although many testbot vms seem to have boot
records after the event log start
    - not sure what the 24 bytes at DataOffset are
    - seems like overkill to fully implement the event log feature, which
generally doesn't seem useful on wine, just for this case
it throws a c++ exception if either method fails
