1. Description of problem: Using ksh across multiple versions of RHEL, customer reports that ksh scripts result in a segmentation fault when "." is in the PATH variable and a sub-process (pwd, ls, etc.) runs in a directory with a .paths sub-directory. 2. Version-Release number of selected component (if applicable): Multiple versions of ksh (I used 20120801-143.el7_9) 3. How reproducible: Always 4. Steps to Reproduce: 4.1. $ export PATH=${PATH}:. 4.2. $ vi crash.ksh #!/bin/ksh mkdir -p OK CRASH/.paths echo "OK case: " 1>&2 ok=$(cd OK; pwd) echo "OK case: pwd=${ok}" 1>&2 echo "crash case: " 1>&2 crash=$(cd CRASH; pwd) echo "crash case: pwd=${crash}" 1>&2 4.3. $ chmod u+x crash.ksh 4.4. $ ./crash.ksh 5. Actual results: OK case: OK case: pwd=/../OK crash case: Segmentation fault 6. Expected results: OK case: OK case: pwd=/../OK crash case: crash case: pwd=/../CRASH 7. Additional info: Customer reports that this occurs in multiple versions of RHEL, and therefore multiple versions of ksh. I performed a similar test in Fedora but did not encounter the reported problem.
