nwc10 | Beware - everything you read on the Internet today is unfunny and untrue. Including this statement. | 06:47 | |

lizmat | I don't agree. It's not funny at all! And true! | 09:10 | |

nwc10 | paste.scsys.co.uk/595028 -- t/spec/S12-attributes/undeclared.t SEGVs spesh | 09:47 | |
attempted NULL pointer dereference. Nothing fishy reported by ASAN or valgrind before this | 09:48 | ||
have not attempted to bisect why this now goes boom | |||
or reduce it | 09:49 | ||
(master/master/master as of right now) | 09:50 | ||
AFK again | 09:51 | ||

dogbert17 dogbert's replication attempts are a total failure :( | 14:32 | ||
nwc10 | I have the 3 environment variables set | 14:33 | |
plus | |||
+#define MVM_ARRAY_CONC_DEBUG 1 | |||
+#define FSA_SIZE_DEBUG 1 | |||
+#define MVM_GC_DEBUG 1 | |||
+#define MVM_SPESH_CHECK_DU 1 | |||
dogbert17 | you've it all it seems :) | ||
nwc10 | but it's probably some combination of MVM_SPESH_BLOCKING=1 and MVM_SPESH_NODELAY=1 | ||
and I've not had time to dig | |||
dogbert17 | will try for a while longer now that I have more info | 14:35 | |
tw, what does ROAST_TIMING_SCALE=8 do? I have never used that. | 14:37 | ||
*btw | |||
nine | Prevents tests from timing out just because rakudo is slowed down by the debugging options | 14:40 | |
dogbert17 | nine, thx | ||
nine | /win 10 | 16:06 | |
dogbert17 | ==655849==The signal is caused by a READ memory access. | 16:19 | |
==655849==Hint: address points to the zero page. | |||

oh, I can even get it to fail on every run | 16:31 | ||
nine | most important step to fix it :) | 16:44 | |
dogbert17 | nine: I simply removed the first seven tests from the file so that there were only four left. That did the trick. | 17:01 | |
followed by 'MVM_SPESH_NODELAY=1 MVM_SPESH_BLOCKING=1 ./perl6-m -Ilib t/spec/S12-attributes/undeclared.t' | 17:02 | ||
