通过symbolicatecrash方式解析后的日志，解不出具体的类和方法，使用项目的版本号：4.2.92

PAG团队-齐国鹏:请问是必现的还是偶现的，如果是必现的可以提供下复现 demo 这样定位会快很多

chenzm:有demo文件，文件比较大，怎么发你

PAG团队-齐国鹏:可以上传到一个 git 仓库，链接发我

chenzm:

找到必现步骤了，podfile中引入 pod 'BaiduMapKit/Map', '6.0.0'，官方demo也会崩溃，依赖的各个库的版本号

• BaiduMapKit/Base (6.0.0)

• BaiduMapKit/Map (6.0.0):

• BaiduMapKit/Base

• ffavc (1.0.1)

• libpag (4.2.92)

• Masonry (1.1.0)

• Toast (4.0.0)

chenzm:

辛苦帮忙看下在pag-ios的demo项目中引入

pod 'BaiduMapKit/Map', '6.0.0'

只是创建pagview，就会出上面的崩溃

PAG团队-齐国鹏:

感谢反馈，问题已经定位到，本周会发布一个版本修改该问题

同时也可以给百度地图反馈这个问题，他们暴露了不需要的符号：

请问这个修复版本号是多少？我们现在用的4.2.110，是否已经带了修复的？目前我这边debug的时候出现一次，不确定是否同样问题

[kevingpqi123]

这个问题是必现的，偶现的就不是这个问题，4.2.100 版本已修复
