Hi Tom, Ulrich and community members,

The reason I could not do it in a simple .exp file is AIX is protecting the current working
directory when I try to delete. It says the requested resource is busy.

So, I had to write a C code the fork () and child will delete the current working directory to mimic another terminal deleting the current working directory.

Then from the parent exec gdb with a binary having dwarf symbols to reproduce the crash.

For example:

bash-5.3# mkdir gdb_test

bash-5.3# cd gdb_test

bash-5.3# pwd

/tmp/gdb_test

bash-5.3#

bash-5.3# rm -rf ../*

rm: cannot remove '../gdb_test': The requested resource is busy.

bash-5.3#

This is the issue. We need to find a way to mimic someone deleting the cwd from another terminal in one test case. In the .exp file from what I know we cannot find a way to delete the current working directory and still start GDB from the deleted directory. Let me know if I am wrong here.

Thanks and regards,

Aditya.
