注意：我正在使用karalabe的xgo为ARM6进行编译

你使用的Go版本是什么( go version )?

$ go version
go version go1.12.17 linux/amd64

这个问题在最新版本中是否重现？

是的，1.12.17和1.14.0似乎都受影响。

你做了什么？

使用github.com/mattn/go-sqlite3进行交叉编译应用程序，仅将其导入armv6,并启用CGO_ENABLED=1
代码：

package main

import _ "github.com/mattn/go-sqlite3"

func main() {
	println("Hello")
}

更长的故事是，我的主机操作系统是macOS,因此我默认使用karalabe/go-1.12.12作为目标。然而，我也在go-1.12.17( cd docker/go-1.12.17 && docker build -t karalabe/xgo-1.12.17 )和最新版本的1.14.0( cd docker/go-1.14.0 && docker build -t karalabe/xgo-1.14.0 )上进行了测试，但没有区别。
我能在三次情况下遇到段错误：

1. 不使用gomod的代码，构建可执行文件的输出将是Segmentation fault
2. 使用gomod(仅go get github.com/mattn/go-sqlite3作为包)的代码，可执行文件的输出将是Segmentation fault
3. 使用gomod(仅go get github.com/mattn/go-sqlite3@v1.11.0作为包)的代码，可执行文件的输出将是fatal: systemstack called from unexpected goroutineSegmentation fault

构建

测试环境

树莓派Zero(非W型)。由于没有互联网，通过交叉编译进行构建。

不使用gomod

构建代码：

$ mkdir diamondo25 && cd diamondo25
# write the main.go file from the code above
$ nano main.go
$ docker run -it -v $PWD:/code/ -w /code/ --entrypoint bash karalabe/xgo-1.12.17  
root@91db62d6dde7:/code# export CC=arm-linux-gnueabihf-gcc-5 GOOS=linux GOARCH=arm GOARM=6 CGO_ENABLED=1

root@91db62d6dde7:/code# CGO_CFLAGS='-march=armv6' CGO_CXXFLAGS='-march=armv6' go install std

root@91db62d6dde7:/code# go get github.com/mattn/go-sqlite3

root@91db62d6dde7:/code# go build -o hello .

root@91db62d6dde7:/code# exit

现在在'diamondo25'文件夹中有一个新的hello可执行文件。
将二进制文件复制到一个armv6l盒子上。运行可执行文件立即报告SEGFAULT:

pi@raspberrypi:~ $ ./hello
Segmentation fault

pi@raspberrypi:~ $ file hello

GDB帮助不大：

使用gomod

$ mkdir diamondo25_gomod && cd diamondo25_gomod
# write the main.go file from the code above
$ nano main.go
$ docker run -it -v $PWD:/code/ -w /code/ --entrypoint bash karalabe/xgo-1.12.17

root@e35c28fde210:/code# go build -o hello .
# Keep open for next variant

现在在'diamondo25_gomod'文件夹中有一个新的hello可执行文件。与之前的无gomod变体相比，此可执行文件的构建时间更长。
运行此代码也报告Segmentation fault

使用gomod with go-sqlite3@v1.11.0

使用Docker容器shell,将go-sqlite3模块更改为v1.11.0

root@e35c28fde210:/code# go get github.com/mattn/go-sqlite3@v1.11.0
go: finding github.com/mattn/go-sqlite3 v1.11.0

go: extracting github.com/mattn/go-sqlite3 v1.11.0

root@c1619b650cc7:/code# go build -o hello .

现在，复制并运行此可执行文件将抛出fatal: systemstack called from unexpected goroutineSegmentation fault错误：

pi@raspberrypi:~ $ ./hello
fatal: systemstack called from unexpected goroutineSegmentation fault

GDB这次报告了不同的信息：

它不清楚实际崩溃的位置，因为它从未报告堆栈。我认为这导致了致命异常。
