Guard static variable first
* ext/openssl/ossl_asn1.c (Init_ossl_asn1): register the static
variable to grab an internal object, before creating the object.
otherwise the just-created object could get collected during the
global variable list allocation. [Bug #16196]

Prefer rb_gc_register_mark_object
* ext/openssl/ossl_asn1.c (Init_ossl_asn1): prefer
`rb_gc_register_mark_object`, which is better for constant

variables which can be re-assigned at runtime. [Bug #16196]

atime may not updated unless strictatime is set on macOS Catalina
Cited from mount(8):
```
strictatime
Always update the file access time when reading from a
file. Without this option the filesystem may default to a
less strict update mode, where some access time updates
are skipped for performance reasons. This option could be
ignored if it is not supported by the filesystem.

fix tracepoint + backtrace SEGV
PC modification in gc_event_hook_body was careless. There are (so
to say) abnormal iseqs stored in the cfp. We have to check sanity
before we touch the PC.
This has not been fixed because there was no way to (ab)use the
setup from pure-Ruby. However by using our official C APIs it is
possible to touch such frame(s), resulting in SEGV.
Fixes [Bug #14834].
Fix assertion failure when VM_CHECK_MODE

Get rid of indirect sharing
* string.c (str_duplicate): share the root shared string if the
original string is already sharing, so that all shared strings
refer the root shared string directly. indirect sharing can
cause a dangling pointer.
[Bug #15792]
str_duplicate: Don't share with a frozen shared string
This is a follow up for 3f9562015e651735bfc2fdd14e8f6963b673e22a.
Before this commit, it was possible to create a shared string which
shares with another shared string by passing a frozen shared string
to `str_duplicate`.
Such string looks like:
```
-------- -----------------
| root | ------ owns -----> | root's buffer |
-------- -----------------
^ ^ ^
----------- | |
| shared1 | ------ references ----- |
----------- |
^ |
----------- |
| shared2 | ------ references ---------
-----------
```
This is bad news because `rb_fstring(shared2)` can make `shared1`
independent, which severs the reference from `shared1` to `root`:
```c
/* from fstr_update_callback() */
str = str_new_frozen(rb_cString, shared2); /* can return shared1 */
if (STR_SHARED_P(str)) { /* shared1 is also a shared string */
str_make_independent(str); /* no frozen check */
}
```
If `shared1` was the only reference to `root`, then `root` can be
reclaimed by the GC, leaving `shared2` in a corrupted state:
```
----------- --------------------
| shared1 | -------- owns --------> | shared1's buffer |
----------- --------------------
^
|
----------- -------------------------
| shared2 | ------ references ----> | root's buffer (freed) |
----------- -------------------------
```
Here is a reproduction script for the situation this commit fixes.
```ruby
a = ('a' * 24).strip.freeze.strip
-a
p a
4.times { GC.start }
p a
```
- string.c (str_duplicate): always share with the root string when
the original is a shared string.
- test_rb_str_dup.rb: specifically test `rb_str_dup` to make
sure it does not try to share with a shared string.

It wrongly used all linenos of ISeq#trace_points which includes not only
line events but also call, return, and other events. So, the result
included some linenos that can not be covered at all by line coverage.

Apparently, a component of Rails implements a buffering .write
method which keeps the String buffer around and makes it unsafe
for us to clear it after calling .write.
This caused Rack::Deflater to give empty results when enabled.
Fortunately, per r61631 / a55abcc0ca6f628fc05304f81e5a044d65ab4a68,
this misguided optimization was only worth a small (0.5MB) savings
and we still benefit from the majority of the memory savings in
that change.
Thanks to zunda for the bug report.
