Issue #17843 has been updated by xtkoba (Tee KOBAYASHI).


I wonder if the problem disappears by backporting commit:4ea96f1d4f8a50c204c4367c994cdbf12cd97b64 which modifies `fill_random_bytes_syscall` so that it calls `CCRandomGenerateBytes` instead for newer environments (probably for macOS >= 10.10).

A quicker workaround would be to apply the following patch to avoid calling `SecRandomCopyBytes`.
```patch

+++ b/random.c
