--- Comment #5 from Vincent Povirk madewokherd@gmail.com --- I'm guessing it's just not getting to your terminal because winedbg prints to the win32 standard output, which was (probably correctly) detached by ShellExecute starting with that commit. There's no reason to expect the stdout stream winedbg inherits from random crashing processes to always be useful, maybe it's a bug that the backtraces go there rather than the Unix stdout.
