Yes, this version works for me.

However, I think there is a point may need to be enhanced:
diff --git a/extensions/libgcore/gcore_coredump.c b/extensions/libgcore/gcore_coredump.c
index e2d9941..fec8ffc 100644
--- a/extensions/libgcore/gcore_coredump.c
+++ b/extensions/libgcore/gcore_coredump.c
@@ -200,7 +200,8 @@ void gcore_coredump(void)
                                        "readmem vma list",
                                        gcore_verbose_error_handle());
                        } else {
-                               pagefaultf("page fault at %lx\n", addr);
+                               if (paddr == PADDR_NOT_AVAILABLE)
+                                       pagefaultf("page fault at %lx\n", addr);
                                BZERO(buffer, PAGE_SIZE);
                        }

Without this, I would see many " page fault at XXX" for the lazy mapping as we talked in the previous thread:
