I think this is a bug in QEMU's ELF loader - it doesn't properly handle
a pure BSS segment (one with file size of 0).  The difference between
2.0.4 and 2.0.5 is that I explicitly disabled PIE which removed some
unused dynamic linking machinery.  These specific test programs now
have BSS but no writable static data.

And I spotted another test program that has this property (setjmptest
on s390x), which also had it when built for 2.0.4.  It also failed in
both versions, but I failed to record this in the table above.

Ben.

You can't have everything.  Where would you put it?
