Bug ID: 49770
           Summary: Firestorm viewer regression after 5.13?
           Product: Wine
           Version: 5.16
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

I have older (by now) firestorm Viewer (Second Life / Open Simulator client)
installed  in my wine prefix. It was working in 5.13, but in 5.15 and 5.16 it
crashes:

invalid adapt mode.

Unhandled exception code c0000005 flags 0 addr 0x175054b

it even crash when I try to get help:

wine Firestorm-Release.exe -h

but slightly differently:

--purge                   Delete files in the cache.
  --qa              ib/javaaC

LLCrashLoggerWindows::processingLoop : Client has connected!
0024:err:seh:NtRaiseException Unhandled exception code c0000005 flags 0 addr
0x175054b

and this makes console (inside Konsole terminal emulator) not very well looking
(try midnight commander) until I 'reset' it by typing reset.

Does this mean it messes up environment variables?

What kind of logs I must create? (sounds like display/adapter regression, but
who knows, may be this message mean something else).
