[ruby/date] Call rb_gc_register_mark_object after object allocation

2025-12-06T17:13:32+00:00

It's possible that both half_days_in_day and day_in_nanoseconds are Ruby
objects, which means that creating day_in_nanoseconds may trigger GC.
Since half_days_in_day is not registered as a mark object until after
day_in_nanoseconds is allocated, the GC may reclaim half_days_in_day.

We can see this crash:

[ruby/date] [Bug #21436] check for fixnum lower bound in `m_ajd`

2025-06-15T16:12:45+00:00

Issue - https://bugs.ruby-lang.org/issues/21436

Apparently, the lower bound check is missing, which results in overflow & wrapping later on in RB_INT2FIX
