Comment(by mwtoews):

 More testing ...

 There is no crash if explicitly casted:
 {{{
 SELECT ST_AsText('POINT(3 4 hi)'::geometry);
 SELECT ST_AsText('POINT(3 4 hi)'::geometry);
 }}}
 but this does crash on the second statement:
 {{{
 SELECT ST_AsText('POINT(3 4 hi)'::text);
 SELECT ST_AsText('POINT(3 4 hi)'::text);
 }}}

 Going through the other output functions with the template:
 {{{
 SELECT <ST_function>('POINT(3 4 hi)'::text);
 SELECT <ST_function>('POINT(3 4 hi)'::text);
 }}}
 Here are the results:
  * ST_AsBinary - good
  * ST_AsEWKB - good
  * ST_AsEWKT - crash
  * ST_AsGeoJSON - crash
  * ST_AsGML - crash
  * ST_AsHEXEWKB - good
  * ST_AsKML - crash
  * ST_AsSVG - crash
  * ST_AsX3D - good
  * ST_GeoHash - good
  * ST_AsText - crash
  * ST_AsLatLonText - good
