endpos->col will be 0 in this scenarios. Substract 1 and it will
become a huge number,
because col is an unsigned int. The correct value for pos would be the
last col of
the previous line. However I am not certain this is the right way to
do this.
There is another problem :
--------------

a
-------------
call search('a\_s*','ew')
will never wrap in this case.
