 # Tests for the special .CURDIR variable.
 
 # TODO: Implementation
 
+# As of 2020-10-04, assigning the result of a shell command to .CURDIR tries
+# to add the shell command to the .PATH instead of the output of the shell
+# command.  Since "echo /" does not exist, the .PATH is left unmodified.
+# See Parse_DoVar at the very bottom.
+.CURDIR!=      echo /
+.if ${.PATH:M/}
+.  error
+.endif
+
+# A normal assignment works fine, as does a substitution assignment.
+# Appending to .CURDIR does not make sense, therefore it doesn't matter that
+# this code path is buggy as well.
+.CURDIR=       /
+.if !${.PATH:M/}
+.  error
