I had a small application that crashed regularly when running standalone but not when I ran inside of
gdb. Following some advice I found in the web, I used
ulimit -c unlimited to generate a full core dump and investigate why the app was crashing. However, both my file browser and my terminal were telling me that the file had 255 GB, but neither my partition nor my entire disk have this amount of free space. Moreover, I don't think it's possible for a 255 GB-file be written in seconds to a regular magnetic hard disk.
Why was this inode generated with such a size?
