Follow-up Comment #13, bug #62040 (project groff):

> Another possibility is to comment out the same line that Jeff did and see if
that makes the problem go away; if it does, then the foregoing may be
unnecessary, as the culprit will be narrowed down.

The line in question was:


diff --git a/contrib/mm/m.tmac b/contrib/mm/m.tmac
index 0a5ab82b0..7b0b27ee8 100644
--- a/contrib/mm/m.tmac
+++ b/contrib/mm/m.tmac
@@ -809,7 +809,7 @@ in=\\n[.i] fi=\\n[.u] .d=\\n[.d] nl=\\n[nl] pg=\\n[%]
 .      sp -1
 .\}
 .sp -1
-\h'\\n[misc*.k]u'\c
+.\"\h'\\n[misc*.k]u'\c
 .rr misc*.k
 .vpt 1
 .\}


This makes no difference to the double-free.
