SLD problem

Hello list,
I'm trying to upgrade MapServer 5.4.2 => 5.6.1, but my
WMS+SLD/WFS-client combination does not work after upgrading. WFS data
is fetched from GeoServer.
This is an obvious explanation from MapServer log:
msEvalRegex(): Regular expression error. String failed expression test.
But why - and how do I get over it?
Note that If I do not use SLD, Mapserver 5.6.1 works fine (see result:
MS561_noSLD_osm_2010.png).
Example request (with SLD parameter):
*************************************
http://10.0.36.146/cgi-bin/osm_2010?LAYERS=planet_osm_line&FORMAT=image%2Fpng&SLD=http://10.0.36.146/sld/osm.xml&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&EXCEPTIONS=application%2Fvnd.ogc.se_inimage&SRS=EPSG%3A4258&BBOX=24.808341477283,60.151299935951,25.017877068694,60.360835527361&WIDTH=265&HEIGHT=265
Request returns SLD -styled map with MapServer 5.4.2 (see
MS542SLD_osm_2010.png)
