在回答中有几个关于“段错误”(Segmentation fault)的好解释,但由于在发生段错误时通常会出现内存内容的转储,我想分享一下“核心已转储”(core dumped)与内存之间的关系: 从 1955 年到 1975 年左右,半导体存储器问世之前,计算机存储器的主导技术是使用铜线串起来的小型磁性圆环。这些圆环被称为“铁芯”,因此主存被称...
exit() means this program is finished, But spawed thread to call imwrite() is running. it is not normal status. So <thread>,join() is needed before exit(). // g++ -g main.cpp -o a.out -lpthread -I/usr/local/include/opencv4 -lopencv_core -lopencv_imgcodecs #include <iostream...
In such a case, the program may crash; however, to avoid a segmentation fault, we have checked if the pointer is NULL or not. NULL means no memory was allocated because the requested space is unavailable. Output: Space is not enough. If you try this code using dynamically allocated ...
Some machines may experience Segmentation Fault, while others do not. If that happens, it usually means you have an issue with your code, and we managed to get away with it on that system by luck. It all relies on how memory is organized and whether or not it is zeroed. We’ll exami...

segmentation fault means that you have touched some memory you should not. In your case it is stack overflow. Part of call stack at the moment of crash:http://puu.sh/jtZwp/273a72aebb.png As you can see there is an attempt to calculate factorial of negative number which leads to callin...
This means that you should be able to isolate the server where the issue happens, determine if the issue is reproducible throughout a cluster of PHP servers, and add instrumentation to that server.Back to top How to Find the Cause of the Segmentation Fault Finding the cause of a ...
What causes segmentation fault 11? When Segmentation fault 11 occurs, it means thata program has attempted to access a memory location that it's not allowed to access. The error can also occur if the application tries to access memory in a method that isn't allowed. ...
