#3994: FreeBSD 32 failure on raster tests
--------------------+---------------------------
 Reporter:  robe    |      Owner:  Bborie Park
     Type:  defect  |     Status:  new
 Priority:  medium  |  Milestone:  PostGIS 2.4.4
Component:  raster  |    Version:  trunk
 Keywords:          |
--------------------+---------------------------
 After @komzpa fixed the brin regress issue, raster regress tests were able
 to run, and crashed thus uncovering a raster gosher (at least fro freeBSD
 32-bit)

 The regress log is long and painful so I'll try to paste the highlights
 from:

 There are a bunch like this with server trying to stand up and then crash
 again.  It's hard to tell which regresses are real or just result of
 server trying to get up from being punched.
