[Kelly] strace step is not hang and I have tr generated.
Looking at the tr file, it appears that there was already a directory confdir3 when you ran the strace step, and this directory messed up the test. Please remove that directory (or rename it) and then re-run the "strace -o tr ./a.out". As before, the strace should also hang so you may need to type control-C to exit it after a while. Look at the resulting 'tr' file and compare it to the compressed file tr.gz I sent you earlier.
[Kelly] The difference of tr output start at: openat(AT_FDCWD, "/lib/x86_64-linux-gnu/libc.so.6", O_RDONLY|O_CLOEXEC) = 3 ==> output from yours openat(AT_FDCWD, "/lib64/libc.so.6", O_RDONLY|O_CLOEXEC) = 3 ==> my output
That difference is unimportant. I'm concerned more about what happens after the long string of mkdir/chdir calls, which should occur once you get confdir3 out of the way.
