Game crashes at start | Segmentation fault with fresh download

[yamil-90]

Describe the bug

i got the following error while trying to start the game, if i ignore it it propagates and causes a segmentation fault

DEBUG : Tried to process terrain at (5,0) of submap of (101,84,-2) but the submap is not loaded. my_MAPSIZE: 11

FUNCTION : ter_id map::ter(const tripoint_bub_ms&) const
FILE : src/map.cpp
LINE : 2016
VERSION : cdda-experimental-2024-08-14-0103 45f35ec

UPDATE: downloaded a newer version to try to solve the issue and before i could transfer the savefile to the newer version got the following error while opening the game for the first time (with no modifications):

The program has crashed.

Hard to do much without a save...
The crash log indicates it's happening during the unpacking of an item_location of the item_on_map type.
However, we can't know if it's a failure to access a legal location or if garbage coordinates have been saved.

In principle it should be possible to rescue the save by locating the item_location in it and erase it or change it to a "nowhere" useless fallback item_location. However, that would require knowledge of which file item_locations are stored in and how to find and manipulate them, neither of which I have.

managed to delete some map files and reduce the savefile size while not changing the error im getting

[PatrikLundell]

I might have good news for you: I managed to load the save without crashing, although it did issue a few error reports. I believe it's another instance of an issue that was fixed recently, #75819, so updating ought to allow you to continue.

tried to download the latest release and i get a segfault from the start, do i need to open a separate issue for this? T_T

edit: forgot to mention that this is with a fresh download with no modifications.

[PatrikLundell]

I'm not sure what the recommended method is, but I'd rename the bug report to reflect the new error and update the body of the report to match that.

It's a different error (in the UI handling) in code that's rough at the moment, due to recent changes and actions to address errors uncovered. It may or may not be OS related.

thanks, i updated the fields

Thanks for the report, but it’s a duplicate of #75818.

[RenechCDDA]

Indeed, duplicate.
