New observation! On my Arch machine which has 5.10.11-arch1-1
And # CONFIG_EXPERT is not set CONFIG_UID16=y (So according to my previous email it not trigger the bug) I’m getting the following strace: $ strace -v -e trace=file ~/sh -c "test -w /home/dongcarl/.bash_profile” execve(<blahblah>) = 0 [ Process PID=404360 runs in 32 bit mode. ] open("/dev/tty", O_RDWR) = 3 stat("/home/dongcarl", 0xffdcd738) = -1 EOVERFLOW (Value too large for defined data type) getcwd("/home/dongcarl", 1024) = 15 stat("/home/dongcarl/.bash_profile", 0xffdcd6bc) = -1 EOVERFLOW (Value too large for defined data type) +++ exited with 1 +++ Not sure hot to interpret this...
