| rjbs | You folks ever have any luck with the problem described here -- www.nntp.perl.org/group/perl.perl5....23113.html ? | 02:10 | |
| hoelzro | o_O | 02:17 | |
| rjbs: my policy of late has been "valgrind first and ask questions later", but I'm guessing that p5p has tried that already =/ | |||
| diakopter | rjbs: are you having a problem on mac? | 02:29 | |
| rjbs: I mean, isn't that post more than a year old? | |||
| rjbs | Still a problem. only with threads + debugging | 02:59 | |

| diakopter | rjbs: oh, I thought you meant lizmat's reference to "rakudo on MoarVM on OS X has some sort of memory corruption issue as well." | 14:42 | |

| jnthn | Generally, I've found that concurrency bugs that only show up under debugging are still bugs that *could* happen in release builds, but timing issues make them less likely. | 15:16 | |

| timotimo | i wonder why that had to add an "-fsanitize=address" in there | 19:43 | |
| i mean, asan worked before, right? | |||
| ilmari | timotimo: because it removed it from the -fno-omit-frame-pointer line | 19:51 | |
| although I'm not certain ubsan requires it | 19:52 | ||
| timotimo | oh! | 19:53 | |
