+Subject: pspp-dump-sav; Fix write past end of buffer in corner case.
+
+If count == 0 and size > 0, then n_bytes is 0, buffer is a 1-byte
+allocation, and the assignment to buffer[size] would write to buffer[1]
+(or past it), which is past the end of the allocation.
+
+Found by Address Sanitizer.

+    segment: Fix behavior when #! line is not new-line terminated.
+    
+    The code here is supposed to maintain a invariant that, when it returns a
+    nonnegative value, it initializes *type, but it failed to do that when a
+    #! line did not end in a new-line.  This fixes the problem.
+    
+    Bug #55101.
+    Thanks for Friedrich Beckmann for narrowing down the problem.
