[Squashfs-devel] unsquashed file doesn't match original

[Bruno W. I. <br...@wo...>]

I received a but report for an unsquashed file not matching the original:
https://bugzilla.redhat.com/show_bug.cgi?id=1141206
I was able to reproduce the issue in f21 (not yet released) both with 
the normal Fedora package and with mksquashfs and unsquashfs built from 
the squashfs master repo. So this bug appears to still be in the 
development version of squashfs-tools. (Or perhaps there is a gcc or 
library issue in Fedora.)

To reproduce the problem run:
yes 3 | dd of=testdata bs=1k count=2M
mksquashfs testdata testdata.img -b 1048576
unsquashfs testdata.img
cmp testdata squashfs-root/testdata

The reporter claims that using the -no-fragments option works around the 
problem, but I haven't tested that.
