背景介绍
事情发生在24年的6月初的时候，笔者一直在Linux客户端开发组，一个中控组的同事过来说中控服务在某台基于国产化ARM64芯片的系统中频繁崩溃，故障现象非常稳定，问我有没有遇到过类似情况，我说没遇到过，由于笔者手头也有着急的项目问题需要处理，后面一段时间也就不了了之了，只是频繁的看到这位同事频繁的在设备所在的设备间和工位之间来回跑（那设备系统的源停止服务了且没装ssh）......
定位过程
在那位同事排查了一段时间后，6月18号，同事突然通过微信发来定位信息和调试崩溃信息，说很奇怪，崩溃点发生在一条if语句中......
当时我也懵了，然后给出了几个排查方案：
- 方案一：检查
0是否被作为了除数 - 方案二：检查是否是
if语句中的函数调用引发的崩溃 - 方案三：多次调试，检查崩溃点是否都在同一位置，若不是，那么其它线程可能存在栈溢出破坏了堆栈
过了一会儿，同事给出了答复：
- 对于方案一：他本人早就排查了，没问题
- 对于方案二、三：他进行了数次调试，确定每次都崩溃在同一位置，堆栈信息中不存在
if语句中的那个函数调用信息
然后我又回去看他发给我的代码位置截图，突然想到一件事情......
最终尝试
我看到代码中进行的是浮点数（double）除法，突然想到早年我从源码编译交叉编译工具链时配置的那些硬件参数，其中就包括硬浮点、软浮点的配置
- 硬浮点：处理器内部实现了浮点运算能力、使用浮点寄存器、使用FPU
- 软浮点：编译器利用底层库提供浮点运算能力，使用整数寄存器，不依赖FPU
所以这款老国产化芯片属于信创早期产物，处理器内部可能不支持浮点数运算。
于是我将猜想告诉同事，找找编译器有没有提供类似启用软浮点的编译参数，死马当活马医，进行最后的尝试。
早期结论
后面忘了过了多久，得到的口头答复是，启用软浮点问题消失，服务不再发生崩溃了。那也就验证了我的猜想，这可能就是在信创早期由于硬件不支持浮点运算埋下的坑
最近的Ai分析（2026.08.21）
通过将堆栈信息交由Ai进行分析，Ai又给出了另一种猜想：
ABI不匹配，底层操作系统是基于软浮点编译的，而MariaDB则是用硬浮点编译。这会导致浮点参数在寄存器传递时发生错乱，直接破坏内存栈，理由是崩溃为段错误（sig 11），而非非法指令错误（sig 4）
通过Ai的分析，可以得出另一种结论，在信创早期，可能有一些系统厂商为了使镜像兼容各种芯片，在编译发行版时使用了软浮点参数埋下的坑
最终定论
虽然Ai分析与笔者早期猜想的底层细节不一致，但我们两者对于浮点运算引起崩溃的结论是一致的，处理方式也是一致的，后续遇到类似问题直接查寻处理器参数、再去编译Demo验证即可
