00:35 p_gimeno   rubenwardy: #8411 looks nearly useless without at least line info. Any chance you can manage a compilation in release mode with debug info? A bit of disassembly might help too. Perhaps this: gdb> disas $rip,$rip+10

00:36 rubenwardy at some point, don't really have the time for that currently
00:36 rubenwardy and good night o/
00:36 p_gimeno   k, good night :)
04:26 ANAND      p_gimeno: Had to sleep a little early yesterday. I managed to set up a new remote and compile your branch, but I'm yet to test it. Will check out the PR and the updated test mod as well. Thanks. :)
08:00 ANAND      p_gimeno: Tested your patch with the auto-rotating blade entity - works pretty well. But it doesn't rotate when attached, as expected.
10:46 p_gimeno   ANAND: yeah, you can try to apply the patch in https://notabug.org/pgimeno/minetest/pulls/5#issuecomment-13501
10:52 ANAND      Oh right :)
21:04 p_gimeno   rubenwardy: does the bus error happen in x86?
21:04 rubenwardy I don't have time to test that
21:04 rubenwardy have you tried reproducing it?
21:05 p_gimeno   the question is if it's an x86 machine the one where you're getting it
21:06 sfan5      paramat: you can "import" a commit using git am on the downloaded .patch file
21:06 sfan5      if you need a previous commit gone use git reset
21:07 rubenwardy p_gimeno: https://blog.rubenwardy.com/2018/06/17/my-computer/
21:08 rubenwardy the laptop not the server
21:08 rubenwardy doesn't happen on the server, presumably because it's in release mode
21:08 p_gimeno   ok, so definitely intel x86... I'm intrigued by what can be causing a bus error there
21:09 rubenwardy it's a 64bit processor
21:13 paramat    ok thanks
21:17 p_gimeno   rubenwardy: yeah, x86_64, but the thing is, in x86 (32 or 64) unaligned access does not cause a bus error, which is the most common cause otherwise, unless a flag is set to request that check - https://en.wikipedia.org/wiki/Bus_error#Causes
21:19 sfan5      p_gimeno: in my experience on ARM, there is no bus error either, it just reads garbled data
21:29 p_gimeno   sfan5: it seems that's right, I've just tested on a RPi
21:32 p_gimeno   well, except I didn't get garbage, I got the contents as if read byte by byte
21:35 p_gimeno   most causes I see are mmap-related, which is why it's puzzling
