compiler warning in call to strncpy

[cosinekitty]

Using gcc 10.2.1 on a Debian Bullseye system, I encounter the following warning:

In function ‘jsonp_error_set_source’,
    inlined from ‘jsonp_error_set_source’ at error.c:17:6:
error.c:25:9: warning: ‘strncpy’ specified bound depends on the length of the source argument [-Wstringop-overflow=]
   25 |         strncpy(error->source, source, length + 1);
      |         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
error.c: In function ‘jsonp_error_set_source’:
error.c:23:14: note: length computed here
   23 |     length = strlen(source);
      |              ^~~~~~~~~~~~~~

I doubt it is anything to worry about, but I thought you might like to know. The complete log of how I did this build is below, in case that helps.

Thanks for creating and maintaining this awesome library!
