main: truncate the tag file failed
An error occurred when I used the following command to build, and the desired answer was not found on the Internet.
Chatgpt told me to run as an administrator, I tried but it didn't work
https://github.com/universal-ctags/citre/issues/123#issuecomment-1127793035 I added "-- kinds-C=- zlD -- kinds-C++=- zlD" according to it, but it didn't work
The result implies that ftell(), a standard C function, returns -1. ftell returns -1 when an error occurs.
ftell() is called indirectly from setTagFilePosition(). When I developed the code, I assumed an error never occurred in the context where ftell() is called.
Could you try reproducing the error with the following short input file (input.c)?
}
With the input, run:
> ctags input.c
I pushed #4012. It is not a fix for this issue. However, it helps us understand what happens when ftell reports an error.
I will merge #4012 in soon.
Merged.
In a day, a new binary executable file that includes #4012 will be pushed at https://github.com/universal-ctags/ctags-nightly-build/releases. I would like you to try the executable. I would like to see the output.

I did this, but there was no error reported，Here is tags output：

I added debug prints that may help us understand what happened.
I really wanted to fix this, but I could not get information. If you can reproduce the issue with a new executable, please reopen this.
