[end of stack trace]
[1] 49713 bus error
Context: I have the Chromium checkout built on a separate, USB-C SSD because my main SSD doesn't have much room.
This has been an issue for the past couple macOS versions and I'm kind of at my wit's end. I'm running a late 2021 MacBook Pro, M1 Max.
Any help would be greatly appreciated! Looking forward to contributing to Chromium :)
Thanks,
Nathan (aka NullSound)

Please look at the library column; we need to look at the last stack frame in the Chromium source code before it goes into the frameworks:
16 AppKit 0x0000000194407800 -[NSImage initWithData:] + 76
17 libui_base.dylib 0x000000010a58ac2c ui::ResourceBundle::GetNativeImageNamed(int) + 840
17 libui_base.dylib 0x000000010a58ac2c ui::ResourceBundle::GetNativeImageNamed(int) + 840
So ui::ResourceBundle::GetNativeImageNamed() is trying to create an NSImage, and that is exploding deep in macOS. Yes, ImageIO shouldn't be crashing on bad data (and you can file with Apple if you want about that), but that implies that your checkout might have some bad bits somewhere. I would double-check your local repo, and verify all your files. Perhaps a clean build would help.
