No. The F77 does not explicitly allow the behaviour discussed in
PR 19425. You've found a bug in g77. From the F77 standard
The form of a SAVE statement is:
SAVE [a [, a]...]
where each a is a named common block name preceded and followed by a slash,
a variable name, or an array name. Redundant appearances of an item are
not permitted.
Dummy argument names, procedure names, and names of entities in a common block
must not appear in a SAVE statement.
A SAVE statement without a list is treated as though it contained the names
of all allowable items in the program unit.
Note the part of redundant appaerances.
