            Bug ID: 2090
           Summary: Suspicious sequence of types castings: memsize ->
                    32-bit integer -> memsize
           Product: PCRE
           Version: 10.23 (PCRE2)
          Hardware: x86-64
                OS: All
            Status: NEW
          Severity: bug
          Priority: medium
         Component: Code

Suspicious sequence of types castings: memsize -> 32-bit integer -> memsize.
The value being cast: '(p - string)'. pcre2_valid_utf.c

See lines 145, 151, 158

I suppose instead of casting to int:

*erroroffset = (int)(p - string);

casting to PCRE2_SIZE should be implemented:

*erroroffset = (PCRE2_SIZE)(p - string);
