Thanks for reporting this bug. I can reproduce it, but given that the
upstream issue has been open for more than a year I doubt it will be
solved soon. I agree that having a silent failure with data corruption
is not nice towards the user, but given that fstransform displays
prominent warnings about the fact that it can easily screw up data, I
think it is not a ground for removing the package altogether. The
package can still be helpful to the users, as long as the users are
aware of the risks connected with it.

So what I would rather do is to modify the starting up message so that
the user is aware that running fstransform in low resources environments
can lead to data corruption. Of course, if the user goes to plumbing
level and manually changes internal options, then risks for breakages is
really to be expected.

Of course a proper fix for the bug would be better, but in the meantime
I think this is enough to fix this RC bug and keep fstransform in the
release without putting to much risk on the users.

Thanks, Giovanni.
