How do I debug a segmentation fault?
Basically this is what happens:
I run my server in background: ./server &
then I run my client: ./client
When I try to login to my server, on correct username and password, everything is okay, but when I type invalid user and password, it results in a segmentation fault.
How do I make the compiler/debugger able to output what error its actually see that causes segmentation core dump.
I know gdb but I try using gdb client but it doesn’t seem to work.
A good idea with segmentation faults is to run the program with
valgrindfor debugging. That way, you’ll often get more detailed information about what caused your segmentation fault. For example, it will tell you if you are reading from uninitialized memory.
