Solution for ubuntu 16.04 segment error (core dumped)

I wrote a test software because of the software requirements. I defined the size of two u8 bufs to be 1280*720*8, which is almost the same as the size of 15M. If there is no error in the syntax, I will report the segmentation error directly. Dump) error. Find the relevant information, record it here.

Here we need to use an instruction under Linux:

ulimit -a

The computer information is as follows:

core file size          (blocks, -c) 0
data seg size           (kbytes, -d) unlimited
scheduling priority             (-e) 0
file size               (blocks, -f) unlimited
pending signals                 (-i) 14694
max locked memory       (kbytes, -l) 64
max memory size         (kbytes, -m) unlimited
open files                      (-n) 1024
pipe size            (512 bytes, -p) 8
POSIX message queues     (bytes, -q) 819200
real-time priority              (-r) 0
stack size              (kbytes, -s) 8192
cpu time               (seconds, -t) unlimited
max user processes              (-u) 14694
virtual memory          (kbytes, -v) unlimited
file locks                      (-x) unlimited

Query the size of the current computer stack (stack), so the name is conceivable, the stack space is used to store data such as arrays, then the segmentation error should be that our storage array exceeds his size, I checked my computer's stack size is 8192, Obviously my 15M is already over, and solving this problem requires an order:

ulimit -s 102400

Change to the size that suits you, here is changed to 100M, then I have no problem with the compilation tool. Of course, this method is only a temporary method. Every time you open the terminal, you need to modify it once. This is more troublesome. If there are friends who know what better way to leave a message below.
