Debugging "index out of range " - suggestions please - can Qt IDE provide more help ?

[AnneRanch]

OK, I know what the error is , what I am asking is
how do you identify the actual code where the error "comes from"?
All I have is the line in header reporting the error. How do I backtrack the actual source of the run time error ? Or is is even possible.
So far I have been stepping thru the code in debug mode , but it is little tedious.

I have several similar test codes and it would be helpful if I could identify the actual line where the "index" out of range is detected.

I know this is C code logical error, I am asking if there is a way to let Qt IDE help identifying the source , not just header line reporting the error.

// test retrieve QStringList local data
 current data size    4
 QStringList  test data  ("address ", "B8:27:EB:11:3F:82")  @ index   1
 QStringList  test data  ("name    ", "ARM")  @ index   2
 QStringList  test data  ("address ", "B8:27:EB:11:3F:82", "    name    ", "ARM")  @ index   3

Use a debugger, take a look in the backtrace from where it comes from.

Hi
As Mr Ehrlicher says, it should be visible in the debugger window

I added some code that crash in maindows and then it looks like this
