Found a similar hit on IBMLink. It refers to something called the PRDT
which has "check characters".

After applying a PTF, attempting to load the newly created
module results in the following abend and message:-
Abend106-20 LINEAR FORMAT PROGRAM MNGT
IEWLSERV RC20 RSN 26130003
CSV031I LIBRARY ACCESS FAILED FOR MODULE BBORJRAS, RETURN
CODE 20, REASON CODE 26130003, DDNAME STEPLIB
The above reason code means check characters in PRDT do not
match text (TRLC_RLD_VER). In reviewing the module information
it appears when the binder encounters a non-zero length
merge class in a program object, but on a relink that class
disappears (probably because the csect that contained it has
been updated and replaced), it still leaves the class list entry
around, which may cause the PRDT check chracters to be shifted
from the expected location and lead up to the load failure.
**
Customers installing WAS PTFs (or even other products that ship
DLLs) may experience load errors during execution such as
EDC5207S LOAD REQUEST FOR DLL LOAD MODULE UNSUCCESSFUL.
In particular errors were reported while attempting to load
module BBOUJSL (but may occur with other modules also)
In order to correct the problem, RESTORE the newly installed
PTFs, apply this APAR fix to the driving system,
REDO is NOT sufficient to build the modules from scratch)

Some customers have also reported abend0c4 from BBOWC2N

also OA09214 which has a Binder fix
