我们通过 gdb 一个 C 程序来检验一下: AI检测代码解析 #include <unistd.h> #include <sys/types.h> #include <sys/stat.h> #include <fcntl.h> int main(int argc, char *argv[]){ char buffer[80] = "/tmp/test"; int fd = open(buffer, O_RDONLY); int size = read(fd, buffer, sizeo...
If an object defines __set__() or __delete__(), it is considered a data descriptor. Descriptors that only define __get__() are called non-data descriptors (they are often used for methods but other uses are possible). Data and non-data descriptors differ in how overrides are calculat...

You can see the page fault handler and the system call handler for write() were called inside the fprintf() call. Also, it can record and show function arguments and return value with -A and -R options respectively. The following example records first argument and return value of 'fib' ...
Whether the caller function or called function (callee) responsibility to remove the arguments from the stack at the end of the call that is the stack cleanup process. The name-decorating convention that the compiler uses to identify individual functions. ...
In most programming languages, this parameter is passed automatically when the functionis called. In assembly language, the call instruction handles passing the return address for you, and ret handles using that address to return back to whereyou called the function from. return value The return ...
EXAMPLE Suppose you have build an executable called hello from the following source: """ #include <stdio.h> void say_hello() { printf("hello, world!\n"); } int main() { say_hello(); return 0; } """ You can then get the call trace via: > gdb -ex 'python execfile("path/to...
One of the questions about classes that new programmers often ask is, “When a member function is called, how does C++ keep track of which object it was called on?”. First, let’s define a simple class to work with. This class encapsulates an integer value, and provides some access f...
Description:When running the test suite in 6.0-rpl locally, I got coredumps inside falcon code during the slave's startup in five replication tests. The coredumps are not repeatable every time. I will attach the stack traces (gdb /path/to/mysqld /path/to/core --eval-command='thread app...
