10:23 <fijal> cfbolz: #2650 looks like a legit JIT bug

10:23 <fijal> something to do with immutable fields

10:24 <cfbolz> fijal: Yay!

10:25 <fijal> yes ok, looks quite obvious from the trace

10:25 <fijal> this is the line

10:25 <fijal> v = reverse(W_Cons(pc + 1, W_Cons(pc + 2, W_Cons(pc + 3, W_Cons(pc + 4, W_Nil())))))

10:25 <fijal> and then the trace looks like this

10:25 <fijal> https://www.irccloud.com/pastebin/8E1unOOx/

10:26 <fijal> so p2 fields are set after the call

10:26 <fijal> WHY?

10:26 <cfbolz> fijal: is that the unoptimized trace?

10:26 <fijal> optimized

10:27 <fijal> unoptimized sets the stuff correctly

10:27 <cfbolz> fijal: wait

10:28 * fijal holds his breath

10:28 <cfbolz> But that is with unroll_safe removed, right?

10:28 <fijal> yes

10:28 <cfbolz> I though it crashes with unroll_safe

10:28 <fijal> reverse is a regular call

10:28 <fijal> no, without

10:28 <cfbolz> Ok

10:28 <fijal> like, the segfault is clearly reproducable and the trace is definitely bogus

10:29 <fijal> it's something off with forcing in some obscure way

10:29 <cfbolz> Yes, why are the set field after the call

10:29 <cfbolz> Anyway, this should fit into a test nicely

10:29 <fijal> yes

10:29 <fijal> great bug report!

10:30 <fijal> how the hell we never found it in the wild?

10:30 <cfbolz> Who knows

10:30 <cfbolz> We didn't prove correctness!

10:30 <fijal> How likely are you to recommend Bitbucket to a friend or colleague?

10:30 <fijal> what the fuck bitbucket

16:31 <cfbolz> fijal: Yay!

16:31 antocuni has quit [Ping timeout: 240 seconds]

16:44 <cfbolz> fijal: I doubt that it's an unroll problem

16:44 <cfbolz> fijal: the trace is also wrong in the preamble

16:45 <fijal> ok

16:45 <cfbolz> it's in heap.py, I suspect

16:45 <cfbolz> the setfields are probably forced by the guard_no_exception

16:45 <cfbolz> but I don't get why the call doesn't force them too

16:53 <cfbolz> fijal: it's some kind of problem in the graph analyzer???

16:57 <cfbolz> confused I am

17:01 <fijal> cfbolz: I didn't check, does that has something to do with _attrs_?

17:01 <cfbolz> it doesn't

17:02 <cfbolz> it's really a logic bug in the effectinfo/heap.py interaction

17:07 <cfbolz> fijal: ok, I have a fix
