#4118: Memory sanitizer warnings
------------------------+---------------------------
 Reporter:  Algunenano  |      Owner:  Algunenano
     Type:  defect      |     Status:  assigned
 Priority:  medium      |  Milestone:  PostGIS 2.5.0
Component:  postgis     |    Version:  trunk
 Keywords:              |
------------------------+---------------------------
 Running liblwgeom with Clang's memory sanitizer (`-fsanitize=memory
 -fsanitize-memory-track-origins=2 -fsanitize-recover=memory`) currently
 throws almost 40k errors.

 - Postgis version: `svn-trunk`
 - Geos version: `3.7.0beta1.r4`

 The idea with this ticket is to start addressing those warnings so
 hopefully this sanitizer can be used to detect possible bugs in the future
 as with `-fsanitize=address` or `-fsanitize=undefined`.
