uses over 50KiB when compiled using the 8-bit library. When PCRE2 is
compiled with its default internal pointer size of two bytes, the size limit on
a compiled pattern is 65535 code units in the 8-bit and 16-bit libraries, and
this is reached with the above pattern if the outer repetition is increased
from 3 to 4. PCRE2 can be compiled to use larger internal pointers and thus
handle larger compiled patterns, but it is better to try to rewrite your
pattern to use
