After recompiling Vim with -D_FILE_OFFSET_BITS=64, everything involving tags break, including the help system. Typing :h, or pressing ^] to jump to a tag, causes Vim to get caught in an infinite loop.
Is there another way to get large file support that works? There's no ./configure argument to enable it, so I just added the above macro definition flag in CFLAGS. The problem with not having large file support is not that I need to edit files larger than 2 GiB, but that ^X^F doesn't expand large files, probably because stat() fails with EOVERFLOW. By the way, this problem was encountered on the following system: OS: Slackware Linux 10.2 Libc: 2.3.5 GCC: several versions: 3.3.6, 3.4.6, 4.1.1 Vim: several versions, including 7.0.0 and 7.0.101 -- Haakon
