+Subject: [PATCH] remove executable flag from .dyninst_heap section
+
+This prevents the library/object with this code from having a segment violates
+the W^X security property for segments as the current setting resulted in
+segment with both the WRITE and EXECUTE flags set.  The function
+mark_heaps_exec() restores execute protection to just the heap arrays.
