+# Bug#12777 Different size shown for VARCHAR(n) columns (with n> 64)
+#           in INFORMATION_SCHEMA
+# This bug was unfortunately (for testers) declared to be no bug.
+# So CHARACTER_MAXIMUM_LENGTH of several <whatever>_CATALOG columns within
+# the INFORMATION_SCHEMA depends on PATH_MAX of the operating system.
+# Workaround for this problem:
+# Get the size of ONE known colum and check the size against some values to
+# be able to use the correct --replace_result statement. Using this only the
+# one pair of 'wrong' values is replaced and not all occurrencies of all
+# possible pairs of values. See bug #12777 for details.
