[Boost-users] [boost-1.33.1] broken mmap_file_iterator in spirit implementation details.

hi all, mmap based file_iterator implementation has a nasty bug. it treats empty files as non-existent. mmap() doesn't map empty files into memory, but boost's implementation omit this little detail of posix specification and return an error. in fact, empty file != doesn't exist. regards, pawel. -- to_be || !to_be == 1, to_be | ~to_be == -1
