Please have a look at this thread:
http://www.mail-archive.com/cygwin@cygwin.com/msg73025.html
I exactly know where the problem lies. It is due to the brain dead
boostfs library. Indeed, I always apply the attached patch to my
cygwin builds and everything works ok. I have been testing this
patch by quite some time now, and never had a problem.
Any objections to apply it? If yes, then I suggest that Bo applies
it as a local patch to his package.
