d3812ca41b Fixed bug #80255 
This was a copy&paste mistake, target_block was used where
follow_block was intended. Also update copy&paste mistakes in
the comments.

2a545ba946 Fix #80175: PHP8 RC1 - JIT Buffer not working 
On Windows, `SUCCESSFULLY_REATTACHED` does not imply that the process
has already been properly initialized; thus we must not skip some setup
steps in `zend_jit_startup()`.

Closes GH-6268.

sure that the free really is the first op.
