There is an active issue about something similar: intel/hyperscan#249

[variar]

Data from github downloads suggests that x86 version of klogg is not very popular:

klogg-20.12.0.813-x86-portable.zip (10,80 MiB) — Downloaded 255 times
klogg-20.12.0.813-x86-setup.exe (8,39 MiB) — Downloaded 197 times

klogg-20.12.0.813-x64-portable.zip (12,55 MiB) — Downloaded 1 007 times
klogg-20.12.0.813-x64-setup.exe (9,68 MiB) — Downloaded 1 701 times

Unfortunately, hyperscan has to be disabled in x86 builds until upstream issue is resolved.

[variar]

Leaving this open to periodically track status of upstream bug.

Consider switching to vectorscan

[variar]

Vectorscan builds are now possible by changing config in cmake. Can be used in 32-bit builds but need more testing.
