            Bug ID: 1663
           Summary: JIT fails for many matching subpatterns
           Product: PCRE
           Version: 8.35
          Hardware: x86-64
                OS: All
            Status: NEW
          Severity: bug
          Priority: medium
         Component: Code
          Assignee: ph10@???

program that shows the erroneous behavior

When PCRE_STUDY_JIT_COMPILE is passed to pcre_study() the following pcre_exec()
fails, when a pattern with many matching subpatterns and a long subject is
given.

The attached program prints `count = -27`. If PCRE_STUDY_JIT_COMPILE is omitted
or the partial subject is repeated less than 1365 times, the expected `count =
2` is printed.
