Actually we need to see the trace of that ORA-07445..
So, the actual reason is "ORA-07445: exception encountered: core dump [kcbhfh()+312] [SIGSEGV]"

This seems caused by a bug (saying this with %70 confidence :)

Applying Latest PSU or RU may fix this.. There is a patch for that as well -> patch# 22761995

Here is a similar bug, appearing on restore -> Bug 22761995 - ORA-7445 [KCBHFIX_TAIL()+31] [SIGSEGV] WHEN RUNNING RMAN RESTORE

We have kcbhfh there in the call stack....

There are some workarounds to be considered as well -> Bug 22761995 - ORA-7445 [kcbhfix_tail] When Running RMAN Restore (Doc ID 22761995.8)

Again! not the same function fails, but it is closely related.. I would apply patch 22761995 (or something like 12.1.0.2.190115 (Jan 2019) Database Proactive Bundle Patch) and retest.
