Comment (by pramsey):

 Can you do a binary search and find the geometry that causes the crash?
 Use limit and offset to search 1/2, 1/4, 1/8 of the data table until you
 find the one record that is causing the problem...
 {{{
 select name,
 st_linecrossingdirection(theline, GeomFromText('LINESTRING(2 53.54,20
 53.54)'))
 from mytable limit 500 offset 500;
 }}}
