It didn't work for me either. I had a hard time figuring out what's wrong and 
what's wrong is the  following line:

"ows_srs" "CRS:84 EPSG:4326 EPSG:32634 EPSG:3857 EPSG:2923"

and more particularly the CRS:84 at the beginning. It confuses mapserver to 
think the order is lon/lat. If you remove it, everything's fine again. This 
might be a bug, or nut, as I recall there's a quite complex explanation 
somewhere in the doc describing the precedence between MAP projection, LAYER 
projection, ows_srs at MAP level, wfs_srs at LAYER level...

(I finally found 
https://github.com/mapserver/msautotest/blob/master/wxs/wfs_200_allgeoms.map 
which is a test with EPSG:4326 data and requests without explicit srsName and 
the results are correct : 
https://github.com/mapserver/msautotest/blob/master/wxs/expected/wfs_200_allgeoms_getfeature.xml 
)
