It is probably the same problem that Arla had some year or two ago:
gcc mmaps the file and assumes it ends with a zero byte, the
file system has to zero out the rest of the block for gcc to work.

I'd say it is a bug in gcc, but it is also a security hole that
you get to see data from someone elses file or from some random
memory page.

I have no idea if and/or when this is fixed in the OpenAFS client.
