And again...
[this message is brought to you by the "my god, I'm coding in C
again, I'm too old for this shit" department]
... it appears reconstruct just blindly re-applied the value of
modseq from the already existing entry without checking if it
was valid.
The attached patch contains my previous patch to fix the
append_copy code path along with an additional check in
reconstruct which will set modseq to 1 if it doesn't
already have a value. Since modseq always starts at 1 and
is increased each operation, I think that's OK for people
running in the CONDSTORE universe as well. It's certainly
fine for those of us where modseq will always be 1.
