I see a lot of errors like this on the console on bootup: [2023-10-24T10:18:29.732918] multi-line-pattern: Error while JIT compiling regular expression; regexp='(?:Exception|Error|Throwable|V8 errors stack trace)[:\r\n]', error='bad JIT option' [2023-10-24T10:18:29.733443] multi-line-pattern: Error while JIT compiling regular expression; regexp='^[\t ]*nested exception is:[\t ]*', error='bad JIT option' [2023-10-24T10:18:29.733742] multi-line-pattern: Error while JIT compiling regular expression; regexp='^[\r\n]*$', error='bad JIT option' [2023-10-24T10:18:29.734039] multi-line-pattern: Error while JIT compiling regular expression; regexp='^[\t ]+(?:eval )?at ', error='bad JIT option' [2023-10-24T10:18:29.734328] multi-line-pattern: Error while JIT compiling regular expression; regexp='^[\t ]+--- End of inner exception stack trace ---$', error='bad JIT option' [2023-10-24T10:18:29.734719] multi-line-pattern: Error while JIT compiling regular expression; regexp='^--- End of stack trace from previous location where exception was thrown ---$', error='bad JIT option' Note that jit is use-masked on riscv for libpcre2. Reproducible: Always Steps to Reproduce: 1.emerge app-admin/syslog-ng-4.4.0-r1 on riscv 2.restart syslog-ng, i.e. '/etc/init.d/syslog-ng restart' 3.

The same on amd64, with dev-libs/libpcre2[-jit]. On one hand, jit can be unmasked on riscv libpcre2 (they added support in 2022), but on the other hand this is an upstream issue of syslog-ng (assuming jit limits hardening and portability). See also https://hup.hu/node/183213 for some analysis.
The pull request mentioned in "see also" was merged into 4.6.0. After emerging app-admin/syslog-ng-4.6.0-r1 the issue is gone.
