13:09:21 <woodser[m]> we're getting a segfault running start_mining on monerod v0.18.2.2 (starting testnet from scratch):... (full message at <https://libera.ems.host/_matrix/media/v3/download/libera.chat/e4dec5c0a15ea677c579b428c0c93a67b8972eb4>)
13:10:18 <sech1> can you get a call stack?
13:13:21 <woodser[m]> can you point me in the right direction to get that? it's not written to a file by default, and not much more is useful in the logs at level 3. something to do with the SANITIZE=ON option?
13:15:27 <sech1> no, just run it under gdb

13:58:40 <selsta> there have been multiple reports about this now but only on testnet hmm
13:58:59 <sech1> yes, I reproduced it
13:59:22 <woodser[m]> hoping to be able to sort this out soon, since it's blocking our release ><
14:06:51 <woodser[m]> nevermind, we can release as-is. but our CI tests are broken until this is fixed :)
14:07:28 <sech1> It tries to allocate RandomX dataset despite first blocks not using RandomX
14:07:50 <sech1> I don't see a place in the code where it doesn't check for used algorithm before doing it
14:08:45 <sech1> So I'll need to investigate
14:13:07 <sech1> okay found it
14:16:49 <woodser[m]> exellent!
14:29:26 <sech1> woodser[m] you can try https://github.com/monero-project/monero/pull/8831
14:29:36 <woodser[m]> ok, trying
14:30:56 <selsta> sech1: can you add Closes #8821 to the PR description? 
14:32:04 <sech1> ok
14:33:01 <sech1> and https://github.com/monero-project/monero/pull/8832 for master branch
14:33:05 <selsta> description, not title
14:33:17 <selsta> otherwise it doesn't automatically close the issue
14:33:25 <selsta> ty
14:54:10 <woodser[m]> yes that works, thank you!
