エラー時の行数表示がおかしい
実際の4倍の行数で表示される。もちろん、なんの改造もしていないOpenHSP ver3.2beta1をコンパイルしたhspcmp.dllなんだけど。
後でHSP ver3.1とプリプロセス済みファイル、オブジェクトファイルを比較してみる。

むう。
プリプロセス済みファイルに違いはなくて、オブジェクトファイルは明らかにサイズが違う。
Debug Infoのサイズが3.1のは137で、3.2beta1のは506ってかなり増えてる。
んー次はOpenHSP ver3.1も手元にあるのでこれでも同じことを試してみようかな。
それでも同じように行数表示がおかしくなるようだったら、自分の環境がおかしい可能性が濃厚になる。
OpenHSP ver3.1RC1で同様のテストを行ってみたところ、プリプロセス済みファイルもオブジェクトファイルもHSP ver3.1と同じ結果で、エラー時の行数表示も正しかった。
次はver3.2beta1とのソースの差分から原因を突き詰めていこうと思う。
その前にOpenHSP ver3.2beta1のランタイムでも同様の不具合があるか確かめるべきだった。オブジェクトファイルのフォーマットに3.1と互換性がないだけかもしれない。
OpenHSP ver3.2beta1のhsp3clやhsp3でも同様にエラー時の行数表示がおかしかった。やっぱり不具合か、自分の環境がおかしいか。他の人も同様の不具合が起きるのか誰か試してくれないかな。自分ひとりじゃ「不具合だ」って報告するにはあまり自信ない。
さて、OpenHSP ver3.1とOpenHSP ver3.2beta1のソースの差分から原因を突き詰めていく作業に入る。
やっぱり最初に疑うべきはDebug Infoに書き込む処理だと思う。
diffをとってそこからdi_bufを検索するとcodegen.cppの2482行目。
@@ -2483,7 +2482,7 @@ int ofs; ofs=(int)( GetCS() - cg_lastcs ); if ( ofs <= 250 ) { - di_buf->Put( (unsigned char)ofs ); + di_buf->Put( ofs ); } else { di_buf->Put( (unsigned char)252 ); di_buf->Put( (unsigned char)(ofs) );
これっぽい感じがする。
さっそく該当箇所を di_buf->Put( (unsigned char)ofs ); に戻してみたところ、エラー行数表示がおかしくなる不具合が直りました。ふうう。さて、次は報告しないとね。
OpenHSPのTracにチケット登録すればいいのかな。
登録した。
