segmentation-fault

问题 I'm trying to add strings to a Binary Search Tree using a recursive insert method (the usual for BSTs, IIRC) so I can later print them out using recursion as well. Trouble is, I've been getting a segmentation faults I don't really understand. Related code follows (this block of code is from my main function): #include <stdio.h> #include <stdlib.h> #include <string.h> #include <ctype.h> // Stores the size of the C-strings we will use; // Standardized to 100 (assignment specifications say //

问题 I am trying to implement the trie as shown on the TopCoder page. I am modifying it a bit to store the phone numbers of the users. I am getting segmentation fault. Can some one please point out the error. #include<iostream> #include<stdlib.h> using namespace std; struct node{ int words; int prefix; long phone; struct node* children[26]; }; struct node* initialize(struct node* root) { root = new (struct node); for(int i=0;i<26;i++){ root->children[i] = NULL; } root->word = 0; root->prefix = 0;

问题 I am calling a function with the following lines: void call_system_command(const char *command_params) { GString *cmd = g_string_sized_new(1024); g_string_append_printf(cmd, "/bin/bash /path/to/my/script '%s'", command_params); system(cmd->str); g_string_free(cmd, TRUE); } I am getting segfault in the line with g_string_sized_new. Backtrace from gdb shows: (gdb) bt #0 0x000000320ce56264 in g_slice_alloc () from /lib64/libglib-2.0.so.0 #1 0x000000320ce5c3db in g_string_sized_new () from /lib64

问题 While figuring out why Eclipse has been crashing on me, I tried to start eclipse and attach GDB to the eclipse java process. However, almost as soon as I attached GDB and told it to continue, there has been a constant stream of segfaults, almost immediately after I continue. This is part of it: Program received signal SIGSEGV, Segmentation fault.

问题 Found this bug, which states the problem as well as I could. https://bugs.launchpad.net/ubuntu/+source/openjdk-6/+bug/732707 The question is - are there any potential workarounds? Thanks 回答1: In the bug report they mention they use IcedTea JVM, not Oracle's one. I've never had this problem with Oracle's, so the workaround: use Oracle's JVM. Also, if you are using version 1.1.1 you should be aware there is a huge security hole, you should update to 1.2.3 ASAP. (latest 1.1.x may have it fixed,

问题 I'm trying to call a global string variable which is defined in a Fortran subroutine, in C. the C code is Cfile.c : #include <stdio.h> typedef struct { int length; char* string; } fstring; extern fstring stringf_; void fortfunc_(); int main() { fstring stringC = stringf_; stringC.string[stringC.length-1] = '\0'; printf("%s \n",stringC.string); return 0; } and FORTRAN code is Ffile.f : subroutine fortfunc() character*30 string common/stringF/ string string = 'this is a string in FROTRAN77'

问题 One of the binaries which I am using in my shell script is causing a segmentation fault (RETURN VALUE: 139) And even though, I am redirecting both stdout and stderr to a logfile, the Segmentation Fault error messages is displayed in the terminal when I am running the shell script. Is it possible to redirect this message from Segfault to a logfile ?? 回答1: The Segmentation Fault message you see is printed by the shell that is running your program. This behavior varies from shell to shell, so a
