| nine | dogbert2: I can reproduce! In rr! while MVM_SPESH_BLOCKING=1 MVM_JIT_DISABLE=1 rr record /home/nine/rakudo/install/bin/moar --execname=/home/nine/rakudo/rakudo-m --libpath=/home/nine/rakudo --libpath=/home/nine/rakudo/blib --libpath=/home/nine/rakudo/install/share/nqp/lib /home/nine/rakudo/rakudo.moarvm -Ilib t/02-rakudo/14-revisions.t ; do true ; done | 09:40 | |
| dogbert2: that's the segfault when reading &ctx->legacy.args[i].o due to garbage in *ctx (version 1 MVMArgs and broken pointers) | 09:41 | ||
| MasterDuke | obvious fix? | 09:51 | |
| nine | if only :) | 10:09 | |
| dogbert2 | nine: very cool, so there's plenty to do while jnthnwrthngtn is on vacation | 10:11 | |

| nine | Good news (for my sanity if nothing else). The missing case MVM_SPESH_ANN_DEOPT_PRE_INS in PEA's add_deopt_materializations_ins is actually critical as well. It's just that we also need to employ MVM_SPESH_ANN_DEOPT_SYNTH to see any difference. | 16:28 | |
| So, yes indeed, to provoke that segfault from a working code base, just remove the case MVM_SPESH_ANN_DEOPT_PRE_INS. | |||
| MasterDuke | any reason not to merge github.com/MoarVM/MoarVM/pull/1472 ? | 16:38 | |
| nine | Not from my side | 16:42 | |
| No Geth? :( | 16:48 | ||
| Geth | MoarVM/new-disp: 3445403032 | (Stefan Seifert)++ | 2 files Fix segfault after deopt due to missing materialization A dispatch op may get replaced with several guards during optimization. When doing this, the first created guard inherits the deopt annotation of the original instruction. Further guards got clones of the annotation. While these clones would point at the correct place in the bytecode to deopt to, they would get newly allocated deopt indexes. PEA materializations are tied to deopt ... (9 more lines) |

| nine | Oh, just slow spesh :) Well, this ^^^ takes care of last weekend's segfault in t/spec/S12-methods/parallel-dispatch.t | ||
| s/slow spesh/slow/Geth/ | 16:50 | ||
| lizmat | actually, it's slow Github Webhooks | 16:52 | |
| www.githubstatus.com shows Webhooks "Degraded" | 16:53 | ||
| nine | Well, better late than never | 16:56 | |
