Hallo, in the Jan97 issue of the Microsoft System Journal there is a "Crash Course on the Depths of Win32 Structured Exception handling" by Matt Pietrek. This article is also available on the web: http://www.microsoft.com/msj/defaultframe.asp?page=/msj/0197/Exception/Exception.htm While the first two examples (myseh.exe and myseh2.exe) run with no different output than on OSR2 on Vmware, showsehframes.exe loops in Wine, dereferencing the code in UnhandledExceptionFilter as a "scopetable" structure: >Frame: 40D56F44 Handler: 40190F10 Prev: FFFFFFFF Scopetable: 40190940 > scopetable[0] PrevTryLevel: 81E58955 filter: 000280EC __except: 53565700 > scopetable[1] PrevTryLevel: 000000E8 filter: C3815B00 __except: 000C012B 0x40190F10 is WINE_exception_handler and 0x40190940 is UnhandledExceptionFilter, probably set up in SYSDEPS_StartThread(). Under OSR2 on Vmware the program terminates here: >Frame: 0063FF68 Handler: BFFB8CF8 Prev: FFFFFFFF Scopetable: BFFB8ED8 > scopetable[0] PrevTryLevel: FFFFFFFF filter: BFF88E98 __except: BFF88EA1 Does Wine need to get compatible on that level too?
