Brian and Greg describe the problem correctly and clearly; you should test to see if any code you're using is impacted. It's very unfortunate to add this restriction, but for the time being, I think its the only reasonable thing to do. Thoughtful arguments to the contrary are welcome, of course. I know how bad this is for some people, but there's a few mitigating factors that I think make it OK for us to do this. -If all goes as planned, this problem will be fixed within a few months time in the upstream GCC (4.4), and backported to MinGW GCC 4.3. -People for whom this is a problem can still build their own GCC with SJLJ enabled. -Throwing non-SEH exceptions through arbitrary foreign frames isn't really a valid thing to do anyway unless you're planning to terminate immediately--and maybe not even then. In the Win32 API case, it appears to work most of the time, but I don't see any guarantee of this documented anywhere. (This problem will by partially mitigated by the forthcoming improvement mentioned above.) -The old GCC 3.4.5 will still be available. ------------------------------------------------------------------------- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.
