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 |

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. :) |

p_gimeno: Tested your patch with the auto-rotating blade entity - works pretty well. But it doesn't rotate when attached, as expected. |

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 |

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 |
| 21:11 |

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 |
