I have a script get_new_GMC.sh that contains this line:
./casm.x < input_to_casm.txt
However, sometimes we might get a segmentation fault (and sometimes we do not)... Sometimes it would have the error:
get_new_GMC.sh: line 156: 72577 Segmentation fault: 11 ./casm.x <
input_to_casm.txt
How could I change my script so that whenever a segmentation fault occurs, I would just rerun ./casm.x < input_to_casm.txt again? Thank you.

The main topic is to write a code in C++ for Hash with Chaining (using single link list).here, data has been provided in terms of array of long datatype and we have to store them in hash(table size 13) in a sorted manner.
Here is my code for the same.

There is no compiler error in the code but while running the code the following error arises.

In line 36 you're calling strcpy(p->name,Name), but Name is passed from x in main, and char x[4] isn't null-terminated as you only assign to x[j] for j from 2 downto 0. Add a statement x[3] = '\0';.
I get the following error when I execute a fortran code compiled with gfortran. The error is followed by a backtrace for this error pointing to memory locations.
Program received signal SIGSEGV: Segmentation fault - invalid memory reference.

Segmentation fault (core dumped)
I would like to know where the first instance of error arises - is it the first line of the backtrace or the lastline? Also, strategies that might help me debug the issue.
Update:
Upon backtracing, the line 90 of instrument involves opening a file like so:
out_file3 = 'new_file'
OPEN(unit=3,file=out_file3,status='unknown')
To determine the issue behind I've incorporated error checking by doing so:
OPEN(unit=3,file=out_file3,status='unknown',iostat=io_status, err=100)
100 write(STDOUT,*) 'io status=', io_status
The code exits with the error:
Error: Invalid value for ERR specification at (1). How do I determine the appropriate value for ERR specification? This led me to suspect that unit=3 might be the cause for error, I've changed the value for unit, but everytime get the "Segmentation fault (core dumped)" error.
Update 2:
OPEN(unit=3,file=out_file3,status='unknown',err=17)
17 write(STDOUT,*) 'Problem'
Still get the Segmentation fault (core dumped) error at the line corresponding to OPEN.... I can only guess that unit=3 is the root cause of the problem.
Update 3
Attempt at a self sufficient example:
character*280 testfile,finalfile,outfile
DIR = '/storage/work/user/'
testfile = 'test.dat'
CALL getenv(DIR,outfile)
CALL sappend(outfile,testfile,finalfile)
OPEN(unit=3,file=finalfine,status='new')
write(3,*) 'Test'
END
I've such code:
print("AAAAAA")
local status, jobj = pcall(json.decode(docTxt))
print("BBBBBB")
decode method causes PANIC error, an it results in following console output:
AAAAAAA
PANIC: unprotected error in call to Lua API (json.lua:166: 'for' initial value must be a number)
Whole program beaks, BBBBB does not get printed to console.
Is this normal? Is pcall broken ?
I was able to figure it out: it can be configured in watchdog options for firmware compiler. Now I've have such setup, that it reboots on panic.

I received a weird error saying

What is this error? How it happened?
It happened when I call session.startRunning() where session is a AVCaptureSession!
