Clang 19 has become more strict about assigning to const variables,
resulting in an error similar to:
/wrkdirs/usr/ports/security/olm/work/olm-6d767aaf29bdf15571c2ef4d3f8f9e953de03733/include/olm/list.hh:106:13:
error: cannot assign to variable 'other_pos' with const-qualified type 'T
*const'
106 | ++other_pos;
| ^ ~~~~~~~~~
/wrkdirs/usr/ports/security/olm/work/olm-6d767aaf29bdf15571c2ef4d3f8f9e953de03733/include/olm/list.hh:102:19:
note: variable 'other_pos' declared const here
102 | T * const other_pos = other._data;
| ~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~
In this case, it looks like a typo: "T * const" means that the pointer
itself is const, thus it cannot be incremented. Instead, this should be
"T const *" (spelled alternatively as "const T *"), which means that the
object pointed to is const, not the pointer itself.
