Bug ID: 55885
           Summary: wine prefix not updated correctly when going back to
                    previous wine version (new wow64, Framemaker 8)
           Product: Wine
           Version: 8.20
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

In the past it was possible to use an existing wine prefix with an older
version of wine: When starting the old wine version, the prefix was updated
according to the old version; It was possible to switch back and forth again.

At least in one configuration I use regulary this does no longer work: After
updating the wine prefix to wine 8.20 switching back to an old version shows
the error

00d8:err:virtual:virtual_setup_exception stack overflow 16 bytes addr
0x7bc543cd stack 0x30ff0 (0x30000-0x31000-0x130000)

It seems that updating the old prefix is only done partially.

I am using the new experimental WOW64 mode, the used program is Framemaker 8
and the old wine version is wine 8.12 (which we use as reference).

It is expected that switching back and forth should work? If yes, I can further
investigate and try to bisect. If this is not supposed to work, please close
this bug report.

Thanks!

I don't know if downgrade is particularly possible to support in general, and
we certainly can't retroactively fix an old release to downgrade correctly. We
may be able to undo whatever broke, but I'm not sure how much of a priority it
can be.

I cannot judge how difficult it is to support this for every thinkable case.
But it worked in the past for many years and is very helpful when bisecting.

I will try to dig into this...

Thanks!

While this should work most of the time, there's no guarantee that it can
always work, particularly when using development snapshots that may introduce
bugs in the prefix.
