Game crashing on M1 Mac

[Lordaeth]

Would really appreciate some help!

I'm on an M1 mac, and I'm playing Austria, 1567 post-revoke (so tons of tiny subject nations). I just accepted a call to arms and my game will regularly crash within 2-3 days of letting it run. I moved graphics down to minimum but it doesn't improve much (changed it from 1 day to 2-3 days). I ported the save to an old Windows computer and it runs just fine (super slow since the computer is old and garbage), even though the Mac has a better CPU and GPU. For some reason, since these crashes started yesterday, just loading a game or launching the game from the launcher will give me ~10 seconds of spinning wheel of death before loading.

One example crash log is attached, although there are dozens.

1. Did I fry/damage my computer somehow?
2. Are there any solutions that will let me keep playing on the mac?

Thank you!

Do all your crashes have the same functions in the demangled stack trace(in your example nanov2_malloc_zero_on_alloc, SDL_Delay_REAL, CApplication::UpdateOneFrame) or are they all different? The current functions seem graphics related(SDL is a graphics library), but it could be memory corruption which results in crashes in random places.

Can you attach your save? I could test if it crashes on Linux and maybe somebody else can test if it crashes on their macOS as well. It could be an OS specific bug in eu4 which you randomly triggered with that specific save or it could be a software or hardware problem on your computer. Or it could be related to the recent steam update in which case it could help to disable the steam overlay for eu4.

@grotaclas

Thank you so much for your response! Looking through, many of the crashes have only one function, which is always the nanov2_malloc_zero_on_alloc.

The save and backup are attached.

Thank you!

Do you think that running it forward a few days and trying again might help?

I tried your save and it crashes for me as well. Interestingly the stacktrace is different on Linux:

  ./eu4                          ( CList<int>::RemoveToEnd(CList<int>::Iterator)  + 0xf   )  [0x194c423]
  ./eu4                          ( CUnit::TruncatePathIfBlocked()            + 0x9b  )  [0x1934f93]
  ./eu4                          ( CCountry::UpdateWarStatus(CEU3Date, bool, bool)  + 0x3fa )  [0x10338ae]
  ./eu4                          ( CWar::AddAttacker(CCountryTag, bool, bool, CEU3Date, bool, bool, EPromiseLand, bool, CWar const*)  + 0x1bd4)  [0x1975660]
  ./eu4                          ( CCallAllyAction::ExecuteDerived() const   + 0x170e)  [0x120ee92]
  ./eu4                          ( CDiplomaticAction::Execute() const        + 0x99  )  [0x11ba3c9]
  ./eu4                          ( CDiplomaticActionCommand::Execute() const  + 0x4d2 )  [0x11bccce]

The good news is that the first three functions are the same as the the stacktrace from this bugreport, so it is likely that your crash is caused by the same bug which just manifests itself differently on Linux and macOS. The developers confirmed that bug, so it will likely be fixed in the next patch, but this might be 1.36 and not compatible with your current save.

As a workaround, you could try to continue your save for a few months on windows and then transfer it back to macOS and see if it works then. Another possible workaround would be to return to version 1.35.3 and see if the save works then. AFAIK the bug was only introduced in 1.35.4.

Absolutely fascinating - changing to 1.35.3 works perfectly (obviously still slow because there are a ton of countries in the war, but absolutely no crashes). Thank you so much for your help!

Having a similar issue, made a post on reddit. I've attached my exception file and save file.

Game version: 1.35.4.0
Platform: macOS Ventura 13.4

I can also confirm that switching to 1.35.3 resolved this issue.

Thank you for posting here like I asked you on reddit. This seems to be the same issue. Interestingly the macOS and Linux stack trace is almost identical this time:
