Golang：致命错误：运行时执行期间出现意外信号 [英] Golang: fatal error: unexpected signal during runtime execution

问题描述

我在执行二进制文件时随机得到以下错误(有时会起作用)：

fatal error: unexpected signal during runtime execution
[signal SIGSEGV: segmentation violation code=0x1 addr=0x47 pc=0x7f07a019b448]

Here is the entire stacktrace.

我运行二进制文件的操作系统版本：

NAME="Ubuntu"
VERSION="18.04.3 LTS (Bionic Beaver)"
ID=ubuntu
ID_LIKE=debian
PRETTY_NAME="Ubuntu 18.04.3 LTS"
VERSION_ID="18.04"
HOME_URL="https://www.ubuntu.com/"
SUPPORT_URL="https://help.ubuntu.com/"
BUG_REPORT_URL="https://bugs.launchpad.net/ubuntu/"
PRIVACY_POLICY_URL="https://www.ubuntu.com/legal/terms-and-policies/privacy-policy"
VERSION_CODENAME=bionic
UBUNTU_CODENAME=bionic

Go版本：

go version
go version go1.16.9 linux/amd64

Bazel选项：

go_binary(
    name = "app-operator",
    embed = [":app-operator_lib"],
    gc_linkopts = [
        "-linkmode",
        "external",
        "-extldflags",
        "-static",
    ],
    static = "on",
    visibility = ["//visibility:public"],
)

我认为它正在发生在这个大猩猩身上：

推荐答案

您应该能够从构建中删除gc_linkopts选项。不真正支持静态链接glibc，可能会导致问题。

如果您有其他需要静态链接的CGO库，则需要专门为这些库提供链接器标志。

如果CGO的唯一用途是在Linux上进行名称解析，当需要静态二进制文件而不需要可移植的C实现时，您几乎总是可以在没有CGO的情况下进行构建，并依赖本机Go实现。
