[ruby-core:108494] [Ruby master Bug#18766] ArgumentError with no backtrace information when requiring openssl/cipher and initializing an OpenSSL::Cipher

technically it does show, the problem are the parameter for initialize, or better for `BasicObject#initialize`
The Error you get is this one:
```
irb(main):001:0> class X
irb(main):002:0> end
=> nil
irb(main):003:0> x= X.new("abe")
(irb):3:in `initialize': wrong number of arguments (given 1, expected 0) (ArgumentError)
from (irb):3:in `new'
from (irb):3:in `<main>'
from C:/Ruby31-x64/lib/ruby/gems/3.1.0/gems/irb-1.4.1/exe/irb:11:in `<top (required)>'
from C:/Ruby31-x64/bin/irb:33:in `load'
from C:/Ruby31-x64/bin/irb:33:in `<main>'
```
because BasicObject#initialize doesn't want any Parameters
now when you require `openssl/cipher` you get a Cipher class using the default ruby alloc with the `BasicObject#initialize`
which of course is crashing when you give them any parameters

Bug #18766: ArgumentError with no backtrace information when requiring openssl/cipher and initializing an OpenSSL::Cipher
https://bugs.ruby-lang.org/issues/18766#change-97539
* Author: postmodern (Hal Brodigan)
* Status: Open
* Priority: Normal
* ruby -v: ruby 3.1.2p20 (2022-04-12 revision 4491bb740a) [x86_64-linux]
* Backport: 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN
----------------------------------------
I discovered a mysterious ArgumentError when requiring 'openssl/cipher' instead of 'openssl' and initializing a OpenSSL::Cipher object. The ArgumentError does not indicate where the exception is being raised from.
## Steps To Reproduce
```
ruby -r openssl/cipher -e "p OpenSSL::Cipher.new('aes-256-cbc')"
```
## Expected Result
```
#<OpenSSL::Cipher:0x000055a5424cef68>
```
## Actual Result
```
Traceback (most recent call last):
2: from -e:1:in `<main>'
1: from -e:1:in `new'
-e:1:in `initialize': wrong number of arguments (given 1, expected 0) (ArgumentError)
```
## Effected Versions
Can reproduce this bug using ruby-2.7 and ruby-3.1.
