Re: [Mono-list] Frequent segfaults in c# running on mono

I just installed the 4.2 kernel and we get the same issue in our code. Interestingly, I wasn't able to reproduce it against 4.1 or 4.2 using the repro test case linked to from that bug. Running 4.09 though, all seems well. Any idea why the fix got rolled back? And when/whether it will be fixed

Ah, of course, thank-you!! We had seen this in the past but not for a while now. It resurfaced when we moved to a new instance, which still had the old kernel. D'oh. Super unfortunate that this appears to be back in 4.1 :(. On 27 November 2015 at 23:10, Matt Calder wrote: >

River, We see seg-faults in multi-threaded code on Ubuntu 14.04 and 14.10. These can be reproduced relatively easily. We believe it is this bug: https://bugzilla.xamarin.com/show_bug.cgi?id=29692 The discussions there will lead you to some discussions about kernel versions. We still see this
