 Priority:  medium                 |   Milestone:  PostGIS 2.0.4

-----------------------------------+----------------------------------------
 Any build of postgis-2.0.3 or source:/branches/2.0 at 11591 on i386 (and
 within a chroot) fails 'make check' for me.

 2.0.3 only fails on lwgeom_regress, r11591 shows the additional 'tickets'
 failure. None of these show up on 64bit builds (i.e. amd64).

 Everything below is from a build of r11591: ./configure says:

 Also note that I initially suspected my own patches for Debian to cause
 this. However, all of the above applies to the unpatched release or svn
 checkout as well.
