Chris already posted that in this thread.     The file does appear to
be sparse.

However, the strace output also looks very unusual ...

... which leads me to on the one hand wonder if the platform is MIPS,
but on the other hand wonder if something else is going on, since the
strace output seems to contain so many unknown errno values and the
strace output doesn't seem to end with an exit syscall.
