I tried to import the Linux kernel repository for a stress test, and I got an error below. Note that 33204 in octal is 100664.

name = 'pijul'
operating_system = 'unix:Unknown'
crate_version = '1.0.0-beta'
explanation = '''
Panic occurred in file '/build/pijul-1.0.0-beta-vendor.tar.gz/git2/src/diff.rs' at line 624
'''
cause = 'unknown mode: 33204'
method = 'Panic'
backtrace = '''
