This bug report mainly shows that GnuCash is "not reporting save
failure".
I think the problem i have has informations to add since
everytime it fails, the data file is exactly 81920B = 80KB large, it
can't be a hazard, maybe something to investigate in that.
Makes me think of a buffer, say 40KB which is committed to disk two
times successfully and then the save aborts for some reason.

Do you remember the size of your corrupted files ?
I don't have time to look at sources to find a save buffer or something,
but i think that if we could find the minimal common multiplier,
which would be equal to the buffer size, of some multiple of it, it'll
probably help the maintainers to locate the bug.

Thank you, the main thing is to remember looking at the file size
_before_ closing GNUCash.
By the way, a big thank to GNUCash for doing that many backup files :-)
