ilogtail-1.8.0 启动报错：Segmentation fault (core dumped)

[LiuShiYa-github]

我在ubuntu 20.04 arm64架构上（实质是Mac book m1上使用VMware Fusion启动的ubuntu虚拟机）尝试使用ilogtail-1.8.0时出现Segmentation fault (core dumped)错误。
下面是出现错误的过程

ilogtail-1.8.0下载地址：https://ilogtail-community-edition.oss-cn-shanghai.aliyuncs.com/1.8.0/ilogtail-1.8.0.linux-arm64.tar.gz

我尝试了使用ilogtail-1.7.1，它是OK的。

我尝试1.8版本的目的是想要使用输出Kafka时支持设置的“数据平铺“功能

@LiuShiYa-github 是否可以在linux arm64上测试一下呢，linux arm64是我们正常的测试环境，但是mac上虚拟机启动这个可能跟linux arm64还是不完全一样

[LiuShiYa-github]

我借用了同事个人的云主机，执行过程如下：

（wget时复制多了wget 指令 但并不影响）

[yyuuttaaoo]

ok，我们用云主机试试看

[yyuuttaaoo]

--ilogtail_disable_core=false生成一下core文件吗

[LiuShiYa-github]

下面是我执行的过程，我并没有看到core文件

root@DorisLog:~/ilogtail-1.8.0# ./ilogtail  --ilogtail_disable_core=false
Segmentation fault (core dumped)
root@DorisLog:~/ilogtail-1.8.0# ls
LICENSE  README.md  ilogtail  ilogtail_config.json  libPluginAdapter.so  libPluginBase.so  user_yaml_config.d

[yyuuttaaoo]

是不是系统没允许生成core文件？
ulimit -c unlimited

[LiuShiYa-github]

好像还是不可以

[root@test ilogtail-1.8.0]# ulimit -c unlimited
[root@test ilogtail-1.8.0]# 
[root@test ilogtail-1.8.0]# 
[root@test ilogtail-1.8.0]# ./ilogtail  --ilogtail_disable_core=false

[yyuuttaaoo]

似乎和tcmalloc链接有点关系，我们解决后发布新的产物

[LiuShiYa-github]

好的，我将关闭该讨论。
感谢回复～ 祝好～
