cobj.exe segfaults on subscript out-of-bounds MOVE on Windows

[ytr-sakamoto]

Parent issue: #828

Description

On Windows, cobj.exe segfaults when compiling test cases where MOVE uses subscripts that are out of bounds.

Affected tests

• tests/run.src/subscripts.at — test cases Subscript out of bounds in MOVE (1), Subscript out of bounds in MOVE (2)
• Currently skipped on Windows via AT_SKIP_IF (introduced in ci: run autotest-based tests on Windows using Git Bash #823).

Environment

• Windows (Git Bash in CI)

Expected behavior

cobj.exe should compile successfully and produce the same runtime diagnostics as on Linux.

Windows 上で cobj.exe が、添字が範囲外の MOVE を含むテストケースのコンパイル時に segfault します。

対象テスト

• tests/run.src/subscripts.at — テストケース Subscript out of bounds in MOVE (1), Subscript out of bounds in MOVE (2)
• ci: run autotest-based tests on Windows using Git Bash #823 にて Windows では AT_SKIP_IF でスキップ中。

環境

期待される動作

Linux と同様にコンパイルが成功し、同じランタイム診断が得られること。
