           Summary: multiple crashes when compiled with ASAN
           Product: PCRE
           Version: 10.32 (PCRE2)
          Hardware: x86-64
                OS: Linux

POC files and the ASAN reports (ending with *.err.txt)

We found with our argumented AFL multiple crashes against an ASAN compiled
`PCRE2 version 10.33-RC1 2018-09-14', by running `./pcre2test $FILE'

Among these, we believe there are some vulnerabilities since most of them are
inside files such as `pcre2_dfa_match.c', `pcre2_extuni.c', etc. A few others
belong to pcre2test.c.
