The following changed when this was first seen, seems related.

Only somehow indirectly since these are codegen changes but the crash is in the optimizer.

I'm not sure that this is the root cause of this defect, but m2v (and v2m, for that matter) should no longer be enabled here, since mstoreiToArray is implemented for all types on PPC. Making that change does seem to prevent this failure from occurring again, at least, so I've opened a PR for it here: eclipse-omr/omr#8078

Closed the PR since the issue seems to be with the new IL opcodes (mloadiFromArray/mstoreiToArray) rather than the old ones (m2v/v2m)

Should be fixed by #23133
