shrayjaiswal050-design opened PR #14780 from shrayjaiswal050-design:fix-cow-order-memory-init to bytecodealliance:main:

Fixes #14585.

Prevents CoW memory images from being created when an active table initializer may trap, so memory remains zero-initialized if startup aborts.

Tests:

• cargo test --test wast -- cow-order
• cargo check -p wasmtime-environ
• cargo fmt -p wasmtime-environ -- --check
• git diff --check
