Comment (by strk):

 Seems to be a robusness issue, because this fails:
 {{{
 ST_closestpointofapproach('LINESTRING M (0 0 1432291464,0 0 1432291536)',
 'LINESTRING M (0 0 1432291464,0 0 1432291466.25,0 0 1432291500)');
 }}}

 While this succeeds:
 {{{
 select ST_closestpointofapproach('LINESTRING M (0 0 91464,0 0 91536)',
 'LINESTRING M (0 0 91464,0 0 91466.25,0 0 91500)');
 }}}

 In the second case I just subtracted 1432200000 from each M value
