Hi Daniweb,
I'm making a shell-ish console for my Operating Systems class. Trying to get the shell to Terminate a process given a process name. Ever since I made the following addition to my code, this error is coming:
- Jun 26, 2017 @jlb: I fixed the out of bounds accesses and recompiled, but the debugger is still telling me the same mistake: program received signal SIGSEGV, Segmentation fault. I am now going to search how to have the debugger tell me exactly where the problem is.
- May 20, 2012 'Program received signal SIGSEGV, segmen 'Program received signal SIGSEGV, segmentation fault' ben1996123 I've never had this problem with any of my other programs. Yes, gridsize is set to 6 when the program reads the file. Is this the exact code you are using? Can't reproduce the segfault.
- The code below is giving me the SIGSEGV error, segmentation fault at line number 66(found using debugger).According to me everything is fine but still don't know what is done wrong by me. Please someone help me out to sort the problem #include.
Program received signal SIGSEGV, Segmentation fault while debugging in codeblocks Hot Network Questions Moving between Schengen Countries. Program received signal SIGSEGV, Segmentation fault. 0x1c0005c2 in main at segfault. C: 6 6. s = 'H'; This code can be corrected by using an array instead of a character pointer, as this allocates memory on stack and initializes it to the value of the string literal.
Program received signal SIGSEGV, Segmentation fault.In __gnu_cxx::__exchange_and_add(int volatile*, int) () ()
The code is here:
Googling has told me that there is some pointer referencing issue going on here. I have tried to pinpoint it but am lost. The thing is, the code runs, the process terminates, the 'cout<<hellow' also executes. However, as soon as it crosses the following brace, the error pops up, ie 'helllllllo' will not print.
Please help me find the source of this issue, thanks

UPDATE: The issue has been fixed. For anyone with a similar issue, this is the article that helped me: '>http://stackoverflow.com/questions/7038124/weird-sigsegv-segmentation-fault-in-stdstringassign-method-from-libstdc
To the best of my (incomplete)understanding, what is happening is that because I declared and initialized the tpid c string on line 43 with ' ', it was fixed with a length of 2, and process names are often longer than that. This resulted in the overflowing of the contents of the array, and then the program crashed when some other variable tried to write itself on top of overflowing elements of tpid.

To solve this, one can either declare the c-string with ample length, or simply declare a pointer to char. Both worked for me

If there is a flaw in my interpretation, PLEASE do let me know to better my understanding of computing. Thanks :)
