and so many.
Remove semicolons following pragma, and repeat the given declaration
at the end to consume a semicolon following the macro call. As many
`NO_SANITIZE` calls including bigdecimal that is a gem have a trailing
semicolon, it was not able to move the semicolon inside `NO_SANITIZE`.
* delete `ar_try_convert` but use `ar_force_convert_table`
to make program simple.
* `ar_force_convert_table` checks hash modification while
calling `#hash` method with the following strategy:
1. copy keys (and vals) of ar_table
2. calc hashes from keys
3. check copied keys and hash's keys. if not matched, repeat from 1
fix [Bug #20050]
st_copy allocates a st_table, which is not needed for hashes since it is
allocated by VWA and embedded, so this causes a memory leak.
The following script demonstrates the issue:
```ruby
20.times do
100_000.times do
{a: 1, b: 2, c: 3, d: 4, e: 5, f: 6, g: 7, h: 8, i: 9}
end
puts `ps -o rss= -p #{$$}`
end
```
Introduce Universal Parser mode for the parser.
This commit includes these changes:
* Introduce `UNIVERSAL_PARSER` macro. All of CRuby related functions
are passed via `struct rb_parser_config_struct` when this macro is enabled.
* Add CI task with 'cppflags=-DUNIVERSAL_PARSER' for ubuntu.
