Subject: [ruby-core:103685] [Ruby master Bug#17843] Ruby on Rails error[BUG] Segmentation fault at 0x0000000000000110 ruby 3.0.1p64 (2021-04-05 revision 0fb782ee38) [x86_64-darwin15] (#42110)

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
--- a/random.c
+++ b/random.c

 # define HAVE_GETRANDOM 1
 #endif

 #elif defined MAC_OS_X_VERSION_10_7 && MAC_OS_X_VERSION_MIN_REQUIRED >= MAC_OS_X_VERSION_10_7
