That failing strcmp may come from stp_tracepoint.c, via

stp_tracepoint_going / get_tracepoint

00126         head =3D &tracepoint_table[hash & (TRACEPOINT_TABLE_SIZE - 1)=
];=20=20=20=20=20

=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20
00128                 if (!strcmp(name, e->name))=20=20=20=20=20=20=20=20=
=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20

=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=
=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20

that offset 0x30 looks like it could be a match for e->name with null e

--=20
