Comment(by realityexists):

 Not sure how I could get a stack trace on Windows, even if I had gdb
 installed, given that there are no PDB files in the Windows PostGIS build.
 I don't have x64 Linux available, only x86 with PostgreSQL 9.2 and it
 doesn't happen there.

 Yes, it does require the fancy function to repro - simply running the
 SELECT returns the expected error every time, no crashes. One slightly
 strange thing I've noticed is that there is sometimes an extra newline
 after the hint, ie.

 {{{
 ERROR:  geometry requires more points
 LINE 1: SELECT 'LINESTRING(0 0)'::geometry;
                ^
 HINT:  "LINESTRING(0 0)" <-- parse error at position 16 within geometry
 <phantom blank line>
 }}}

 Probably unrelated, but that extra new line shows up maybe 1-2 times out
 of 10 attempts. That's running from pgAdmin, so possibly a pgAdmin issue.
