#4353: Backend crash using ST_Buffer
---------------------+---------------------------
 Reporter:  strk     |      Owner:  pramsey
     Type:  defect   |     Status:  new
 Priority:  blocker  |  Milestone:  PostGIS 3.0.0
Component:  postgis  |    Version:  trunk
 Keywords:           |
---------------------+---------------------------
 It looks like someone changed the API of a C function, resulting in a
 backend crash upon using ST_Buffer old signature:

 ==8887== Invalid read of size 1
 ==8887==    at 0x5442B0: pg_detoast_datum (in
 /usr/lib/postgresql/9.6/bin/postgres)
 ==8887==    by 0x19D7D2A6: buffer (lwgeom_geos.c:809)
 ==8887==  Address 0x0 is not stack'd, malloc'd or (recently) free'd

 NOTE: I'm using old signature because upgrade fails (see #4353)

 Signature was changed in r17300 so Paul: it is in your plate to fix!
