It should include footprint size and a RAM size ... for example if my application is like below .. #include <stdio.h> int global = 10; /* initialized global variable */ int test_code(void) { static int i = 100; /* Initialized static variable*/ return 0; } Output: [putta@linux]$ gcc memory-layout.c -c memory-layout [putta@linux]$ ls -ltrh memory-layout.o 760 Nov 9 18:26 memory-layout [putta@linux]$ size memory-layout.o text data bss dec hex filename 67 8 0 75 4b memory-layout.o So now which

Do I need to use the original executable and supply the core, or is there some other way to do it? Using valgrind as the root executable doesn't seem to work, and using the executable that was being run under valgrind directly in GDB with the core seems to produce bad backtraces. 回答1: This works fine for me: gdb ./a.out vgcore.21650 and that's how you are supposed to use the vgcore. If your program corrupted stack before crashing, then obviously you wouldn't get good

I am using Ubuntu 10.04 and I have a program a.c , please help me out. 回答1: Try this: valgrind --leak-check=full -v ./your_program As long as valgrind is installed it will go through your program and tell you what's wrong. It can give you pointers and approximate places where your leaks may be found. If you're segfault'ing, try running it through gdb . 回答2: How to Run Valgrind I would like to build on RageD's

I have created a buggy program - buggy.c - this is a buffer-overflow scenario for buffer t. You can see that I am writing more than 5 indexes. It works fine. It never throws me an error. I was wondering, why is it like that? I tried even Valgrind, this also couldn't find this issue. Can you tell me please what is the issue here? void buffer_overflow(void) { int t[5]; int i = 0; for(i = 0; i<=7; i++) { t[i] = i; } /** this will cause buffer overflow **/ printf("Memory_overflow_completed\r\n"); } int main(int argc, char **argv) { buffer_overflow(); return 0; } $gcc -g buggy.c -o buggy.out

I'm writing an application in C++ which uses some external open source libraries. I tried to look at the Ubuntu System Monitor to have information about how my process uses resources, and I noticed that resident memory continues to increase to very large values (over 100MiB). This application should run in an embedded device, so I have to be careful. I started to think there should be a (some) memory leak(s), so I'm using valgrind. Unfortunately it seems valgrind is not reporting significant memory leaks, only some minor issues in the libraries I'm using, nothing more. So, do I have to

I cannot install Valgrind on macOS High Sierra. It's not available through brew . I've tried with 3.10 . After make install , I get this message: configure: error: Valgrind works on Darwin 10.x, 11.x, 12.x, 13.x and 14.x (Mac OS X 10.6/7/8/9/10) Homebrew says: valgrind: This formula either does not compile or function as expected on macOS versions newer than Sierra due to an upstream incompatibility. Error: An unsatisfied requirement failed this build. Yuriy Lesyo I had the problem like this. So, I found the solving. You should install valgrind by this code brew install --HEAD valgrind I have
