我们通过 gdb 一个 C 程序来检验一下: #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, sizeof(buffer)); c...
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' ...
// Construct this in Global scope instead of within `disarm` // where it will be only initialized first time `disarm` is called. // This increases the likelihood `noop_vtable` lives longer than // any object that refers to it. // If `noop_vtable` goes out of scope first, other obj...

gdb uses system-specific ways to get the function's addresses, but loads the compiler-generated debug info (including the calling function's name) from the executable. In your own code, you cannot even assume that your own program can read itself, let alone rely on a specific debugging form...

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 calculated with respect to entries in an instance’s dictionary. If an instance’s dictionary has ...
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...
