That's definitely very odd. Are you sure that the file is valid? Does 
the following command work? It should dump the coordinates/attributes of 
all the features in the file:

   ogrinfo test.tab test

Try using the following connection strings, just in case:

     CONNECTION "C:/tmp/ms_tmp/mapinfo/test.tab"
or
     CONNECTION "/tmp/ms_tmp/mapinfo/test.tab"

Another thing you could try would be to load and draw the mapfile using 
the mapserver/mapscript/php3/examples/the test_draw_map.phtml test 
script that comes with the MapServer source.

If none of the above works then you might have to file a bug with a copy 
of your mapfile and TAB data file to reproduce this with the 
test_draw_map.phtml.
