Hi!
I think that the root of the problem is that the shell function
_tst_init_checkpoints() does not create the IPC region with the magic.

What about this patch:

diff --git a/testcases/lib/tst_test.sh b/testcases/lib/tst_test.sh
index c32bd8b19..a310d3922 100644
--- a/testcases/lib/tst_test.sh
+++ b/testcases/lib/tst_test.sh
@@ -627,6 +627,7 @@ _tst_init_checkpoints()
                tst_brk TBROK "tst_getconf PAGESIZE failed"
        fi
        ROD_SILENT dd if=/dev/zero of="$LTP_IPC_PATH" bs="$pagesize" count=1
+       ROD_SILENT printf LTPM | dd of="$LTP_IPC_PATH" bs=1 seek=0 conv=notrunc
        ROD_SILENT chmod 600 "$LTP_IPC_PATH"
        export LTP_IPC_PATH
 }
