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!
