Bug#1108530: e2guardian crash with segfault

[Craig Holyoak]

I'm experiencing what I believe is the same issue. In my testing the
segfault is occurring in the libpcre2-posix library. It looks like the
Debian package was minimally patched (1003_pcre2.patch) to compile
against the newer library but there are apparantly breaking changes
between the two (acknowleged upstream at
https://github.com/e2guardian/e2guardian/issues/849).

For now I'm testing to see if avoiding regex lists in the config will
prevent the crashes, or whether the dependency runs deeper than that.
