Hi Daniweb,

Signal Sigsegv Segmentation Fault

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. I am trying to write a program that calculates the product of two large, dense matrices. 'Program received signal SIGSEGV, Segmentation fault.' Program received signal SIGSEGV, Segmentation fault while debugging in codeblocks. What is a segmentation fault?

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:

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 /mdavstfxwin-zip-download.html.

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