OK, this is what happened. The "dump analyser" is a trusty clist written for IPCS by me over 20 years ago. It (almost always) works by using the chain: ASXB -> abending TCB -> RTWA, from where it gets the PSW and registers. In this case it got caught out because there was a preceding TCB with a completion code of 0C1 but only a PRB, no RTWA and hence the mayhem.
So, sorry for the noise but this exchange has proved very useful because I now know about the BEAR. Unfortunately it is not listed by either the IPCS STATUS or SUMMARY commands, which would have been very useful since there is a chain of control blocks to follow (SDWAXPAD->SDWAPTRS, SDWAXEME->SDWARC4).

Even after reading my Principle of Operations, it is still a good catch :-) Of course, the OP discovered later that 'dump analyser picked up the wrong PSW '. I wish the OP published the CORRECT dump results including the PSW and the registers.
