With current CVS wine, my test program breaks into the debugger when it should result entirely in handled exceptions. The test actually triggers a bug in the C library (including MSVCRT.DLL) from Visual Studio 6 SP3 and later, which is only fixed in the MSVCRT.DLL from Windows XP: the destructor for a re-thrown object gets called twice, which results in the last line ending in -1 rather than 0 as it should. Wine starts out like XP, avoiding the first (incorrect) destructor call, but fails to make it all the way back out of main. I have attached (inline) the source, the output on Windows 2000 (wrong), the output on Windows XP (correct), and my results from Wine (debugger). Also, in a zip file is the executable with debug info. // // Exception-handling test // written 2003 by John K.
