fix(checker): keep entity iteration valid across a scope map rehash
 2026-09-21 06:59:02 -07:00
alyekypo 23cc994255 fix(checker): keep entity iteration valid across a scope map rehash 
`check_scope_decls` iterates a scope's entity map while
`check_entity_decl` can insert into that same scope: a procedure alias
(`f :: e`) goes through `override_entity_in_scope`, which calls
`scope_map_insert`. The map grows at 75% load (12 of 16 slots, then 24
of 32), and `scope_map_insert` grows before it probes for the key, so
even an alias that only replaces an existing value rehashes and
reallocates the table in the middle of the iteration.

`ScopeMapIterator` re-read its map on every step while `end` had
captured the capacity at loop start, so the walk continued over the new
table under the old sentinel: it ran past the end of the reallocated
table and dereferenced whatever followed it as an `Entity *` - a nullptr
dereference for a procedure scope holding exactly 12 or 24 entities - or
it stopped at the stale end index and silently skipped every declaration
that the rehash had moved behind it, which left unused declarations
without any diagnostic at all.

The iterator now snapshots the table pointer and capacity when it is
constructed, so iteration is invariant under any insert or grow and
cannot leave the table it began on. A scope that does not grow behaves
exactly as before: the snapshot points at the same table.

gingerBill 654b3a8895 asm: Generalize memory operand syntax to a flat term list 
Parse `[...]` as `term { (+|-) term }` where each term is `operand [ (*|<<|>>) operand ]`.

This allows for constant-only terms to be folded in-place, especially for things like displacement.

e.g. `[p + 8*32]` means `[p + 256]`.

Term order is also free: `[8 + p]` == `[p + 8]`
