Martijn Dekker 5ee290c7a8 cd: Fork if $PWD exists but is not actually the PWD (re: d1483150) ... Commit d1483150 did not fully fix #153. Test case from Harald van Dijk that was still failing: $ mkdir test $ cd test $ rmdir $PWD $ mkdir $PWD $ ksh -c "(cd /); pwd" / Forking a virtual subshell in that case is needed to avoid ending up in a directory that replaced the PWD, because it will not be possible for a process to change back to the original directory. src/cmd/ksh93/bltins/cd_pwd.c: - When deciding whether to fork, instead of attempting to opendir the PWD, compare the inodes $PWD and "." to determine if $PWD still actually refers to the current directory. This uses the test_inode() function which is also used by 'test foo -ef bar'. src/cmd/ksh93/tests/subshell.sh: - Add test based on the above.
