After some frustration, I discovered that I could fix the crashes by defining BOOST_NO_STD_ALLOCATOR -- a flag currently defined for msvc8, but not msvc9. I'm fairly sure that these crashes are due to some subtle bug in the microsoft compiler -- though how said bug is related to the std allocator issue is unclear to me. I've included a small test file and msvs project file that replicate the crash. I'm running against the boostpro packaged windows installers for 1.38 -- I'm afraid I'm too pressed for time atm to compile the latest sources myself. As best I can tell, there have been no changes in 1.39 or the svn that would address this bug, but, if it has been fixed in the latest versions, I apologize.
