thread 1 received signal sigsegv, segmentation fault. 文心快码BaiduComate 什么是"segmentation fault"(段错误)以及它通常是如何发生的? "Segmentation fault"(段错误)是指程序试图访问其内存空间中未分配(或无权访问)的内存段时,由操作系统抛出的错误。这种错误通常发生在以下几种情况: 解引用空指针:尝试访问一个...

报错信息Program received signal SIGSEGV, Segmentation fault,存在内存泄漏 从xpdf/Parse.cc 94行的makeStream调用,一路跟着报错往下翻就会找到这个套娃,这里就不细说了。 下个xpdf4.02源码对比一下就好,修复方式比较简单,加了个变量,记录循环次数,超过一定次数就结束进程。
SIGSEGV 这一信号非常常见,当应用程序对内存的引用无效时,操作系统就会向该应用程序发送该信号。引起对内存无效引用的原因很多,C语言中引发这些事件往往是解引用的指针里包含了错误地址(譬如,未初始化的指针),或者传递了一个无效参数供函数调用等。该信号的系统默认操作是终止进程。 SIGUSR2 与SIGUSR1信号相同。 SIGPIP...
