The point is that there are still people working on 3.x that want this to be fixed and I didn't want to create execve hooks that late on a branch (especially without it first being in -current). > The description misdiagnoses the reason for the exception.

I read (hopefully) most messages that discuss the change and my general impression was that people thought it was a good change. And since the change fixes the Linuxulator related coredumps, I MFC'd it. I didn't base my decision on floating-point examples. The discussion made it clear that it's a subtle issue and a 3/4 line FP program doesn't really tell the complete story.

I was not aware that 3.5 was the last release. I'll back it out if requested, but that also implies that the Linuxulator will be broken again (remain broken, depending on how you look at it), because I'm also not going to spend the needed time to fix the Linuxulator on a "dead" branch. -- Marcel Moolenaar mail: marcel@cup.hp.com / marcel@FreeBSD.org tel: (408) 447-4222 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
