Bug ID: 35928
Summary: Crash handlers/debuggers fail to display
user-interface when invoked for crashing
(non-interactive) service processes (inherited Wine
service window station/desktop)
Product: Wine
Version: 1.7.16
Hardware: x86
OS: Linux
Status: NEW
Severity: normal
Priority: P2
Component: -unknown
Assignee: wine-bugs at winehq.org
Reporter: focht at gmx.net
Hello folks,
bug 35924 is about a crash in a win32 service which triggers 'winedbg'
just-in-time debugger/crash handler.
Unfortunately 'winedbg' fails to bring up its user interface hence you don't
get a chance to see/save the crash info.
The win32 service is connected to Wine's default service window station and
desktop '__wineservice_winstation\\Default' objects (invisible).

When 'winedbg' is spawned from crashing non-interactive win32 service process
it inherits the parent window station object.
Not sure how this scenario should be handled .. making an exception and giving
'winedbg' the default interactive window station/desktop or forcing 'winedbg'
to non-ui mode to have at least a console trace?
