go 1.17.2でSIGSEGVが発生する現象を解消
ginとsqlite3のパッケージを同時に利用するとgo 1.17.2でSIGSEGVが発生していました。
どこに原因があったかわかりませんが、以下の手順で解消しています。
以下のようにginとgo-sqlite3を含むパッケージをビルドし、実行すると以下の通りSIGSEGVが発生しました。
import ( "database/sql" "github.com/gin-gonic/gin" _ "github.com/mattn/go-sqlite3" )
[GIN-debug] [WARNING] Creating an Engine instance with the Logger and Recovery middleware already attached.
[GIN-debug] [WARNING] Running in "debug" mode. Switch to "release" mode in production.
- using env: export GIN_MODE=release
- using code: gin.SetMode(gin.ReleaseMode)

以下のサイトでgo 1.16にdown gradeして解消したという記事を見つけました。
importするパッケージの前にアンダースコアをつけるとunexpected signal during runtime executionが起こる
go 1.18がすでにリリースされているので、バージョンによる問題であれば、
最新バージョンで解消するかもしれないと考えgo 1.18にupgradeしてみました。
update後にビルドしたところ以下のエラーが発生するようになりました。

このエラーについては以下のサイトに解決策が紹介されていたので、この手順を試しました。
go get -u golang.org/x/sys
私の環境ではこの手順で最初に発生していた「SIGSEGVが発生する現象」は解消しました。
