This looks like a problem with the PCRE Lua library. Almost certainly not due to osm2pgsql. I am closing this here, I suggest debugging that at giggls/osml10n#31. If it turns out it was due to osm2pgsql, reopen here or open a new issue.

Unfortunately I can not reproduce your issue on my development environment (Debian 12).

As @joto suspected this might be related to PCRE Lua library I just pushed a commit to master which gets rid of this library and uses native lua patterns instead. Please give it a try.
