Hi, we saw a similar crash when testing with AnyEvent 7.13, Net-SSLeay 1.78 and openssl-1.1.0-pre5. But we dont see it with the current latest openssl-1.1.0b So, looks like it may be a bug in the prerelease openssl 1.1.0? Cheers.

SIgh: havent been able to get Fedora Rawhide netinst to boot in my VirtualBox VM (Fedora 25 netinst is OK!) So I wont be able to make any progress on this for another 2 weeks as I am travelling. Cheers, On Wednesday, November 02, 2016 04:11:45 AM paul@city-fan.org via RT wrote: Show quoted text

Hi again Paul, finally got Fedora Rawhide netinst i386 of 20161031 installed on real hardware :-( again, testing with openssl-1.1.0b Net-SSLeay-1.78 and AnyEvent-7.13 (all compiled locally in a test area) showed no crash in AnyEvent t/80_ssltest.t I saw the same result with Fedora 25. Are you sure your tests have been done with these versions? Cheers. On Thursday, November 03, 2016 05:10:38 PM Mike McCauley wrote: Show quoted text

Well this is interesting. I've just tried again and an i386 build succeeded but the x86_64 build failed: http://koji.fedoraproject.org/koji/taskinfo?taskID=16560073 If you look at the x86_64 build (http://koji.fedoraproject.org/koji/taskinfo?taskID=16560075), you can see what was installed in the root.log file, and the output from the build in the build.log file. We're now on openssl 1.1.0c but the failure was the same as before.

Sigh, Ive been trying to install Rawhide x86_64 20161121 on real hardware but it crashes in anaconda during install. The previously known good rawhide netinst images are no longer available, so I am stumped. Every way I turn to test this bug (if bug is what it is) it disappears before me. I wonder if maybe this is an artifact of your testing environment? Cheers. On Tuesday, November 22, 2016 03:10:59 AM paul@city-fan.org via RT wrote: Show quoted text

Perhaps try the Fedora 25 x86_64 installer and then use dnf to upgrade to Rawhide (https://fedoraproject.org/wiki/DNF_system_upgrade)? Show quoted text

That's always a possibility but I do my testing by installing into a clean chroot all the dependencies and then do the build there, and using that method I always get the same result. My colleague (who provided the backtrace) was also able to reproduce it. Cheers, Paul.

Hi Paul, Sigh, I tried the Point installer to Rawhide option as described on https://fedoraproject.org/wiki/Releases/Rawhide It failed part way through the software download. It failed to download gnome- software, and reported that it tried all the mirrors. Sounds like some sort of problem in the rawhide package repository. There was no option except to exit the installer. Im finding this very frustrating and time consuming for something which may not even be a bug in my software. Can you offer me a reliable way to reproduce this problem? Cheers. On Wednesday, November 23, 2016 03:19:59 AM you wrote: Show quoted text

Great, but its a shame they didnt see fit to remove the disparaging remarks, and to use the symbolic constants (which were added in 2012) instead of '1|2', Cheers. Show quoted text
