If you want to process -regular expressions that are truly enormous, you can compile PCRE with an -internal linkage size of 3 or 4 (when building the 16-bit library, 3 is rounded -up to 4). See the \fBREADME\fP file in the source distribution and the -.\" HREF -\fBpcrebuild\fP -.\" -documentation for details. In these cases the limit is substantially larger. -However, the speed of execution is slower. -.P -All values in repeating quantifiers must be less than 65536. -.P -There is no limit to the number of parenthesized subpatterns, but there can be -no more than 65535 capturing subpatterns. -.P -There is a limit to the number of forward references to subsequent subpatterns -of around 200,000. Repeated forward references with fixed upper limits, for -example, (?2){0,100} when subpattern number 2 is to the right, are included in -the count. There is no limit to the number of backward references. -.P -The maximum length of name for a named subpattern is 32 characters, and the -maximum number of named subpatterns is 10000. -.P -The maximum length of a name in a (*MARK), (*PRUNE), (*SKIP), or (*THEN) verb -is 255 for the 8-bit library and 65535 for the 16-bit library. -.P -The maximum length of a subject string is the largest positive number that an -integer variable can hold. However, when using the traditional matching -function, PCRE uses recursion to handle subpatterns and indefinite repetition. -This means that the available stack space may limit the size of a subject -string that can be processed by certain patterns.
