wasm loader: Fix several issues in GC and exception handling #3586

Closed wenyongh closed 3 days ago

wenyongh commented 6 days ago

Fix several issues of GC and exception handling in wasm loader:

Should restore param_reftype_maps/param_reftype_map_count/param_count in the handling of opcode throw
Should set wasm_ref_type when pushing param types of tag type and block type if the type is a multi-byte type
Should set init_values.data as NULL for opcode struct.new_default in load_init_expr

This PR fixes the issues reported in #3411.
