Segmentation fault (core dumped) error when I excute too

Reboot is a valid approach after (corrected) hardware issues, but a segmentation fault is 99.9% sure to be a software coding problem which will NOT be solved by a reboot, but just hidden for a while longer. A more reasonable reaction might be to document the time, and take a quick system snapshot of sorts with 'vmstat', sar or similar, to get Segmentation faults can also occur independently of page faults: illegal access to a valid page is a segmentation fault, but not an invalid page fault, and segmentation faults can occur in the middle of a page (hence no page fault), for example in a buffer overflow that stays within a page but illegally overwrites memory. There are enough definitions of segmentation fault, i would like to quote few examples which i came across while programming, which might seem silly mistakes, but will waste a lot of time. you can get segmentation fault in below case while argumet type mismatch in printf. #include int main(){int a = 5; printf("%s",a); return 0; } Common segmentation fault scenarios: Modifying a string literal : The below program may crash (gives segmentation fault error) because the line *(str+1) = 'n' tries to write a read only memory. filter_none. edit close. play_arrow. link brightness_4 code. int main() { char *str; The typical action that Linux-based systems take in the event of a segmentation fault is to terminate the execution of the offending process that initiated the condition. Along with halting the program or process, a core file or core dump will often be generated, which is an important tool in debugging the program or finding the cause of the Program received signal SIGSEGV: Segmentation fault - invalid memory reference.

Segfaults are caused by a program trying to read or write an illegal memory location.

My code makes "Segmentation fault". I search this problem in website,so thereforeI have to raise the stack limit. Would you let me know how to increase it? or do you have someoption for compile command? I use the bash shell for RHEL4.0. Thanks Message Edited by hydrol88 on 05-23-200603:00 PM

From this little snippet, it could be anything. All we can tell from this is that something goes wrong when apt-get tries to update its package

Segmentation faults are commonly referred to as segfaults. There are four common mistakes that lead to segmentation faults: dereferencing NULL, dereferencing an uninitialized pointer, dereferencing a pointer that has been freed (or deleted, in C++) or that has gone out of scope (in the case of arrays declared in functions), and writing off the
