 Winnie 32-bit runs have been crashing intermittenly on CUnit.
 Unfortunately it crashes on my pc as well when running mingw in 32-bit
 mode.

 On winnie it crashes more often than not crashing here:

 {{{

   Test: test_lw_dist2d_arc_arc ...passed
   Test: test_lw_arc_length ...passed

 make[1]: Leaving directory `/projects/postgis/branches/2.2/liblwgeom'
 GNUmakefile:14: recipe for target `check' failed

 }}}

 On mine it consistently crashes here:


 {{{

 }}}

 and if I remark out the crashing tests, it just crashes on the next one.

 I did notice some odd code around misc_suite.  That suite seems to be
 defined twice at

 line 163 in liblwgeom/cunit/cu_misc.c

 Not sure if there was a reason for that.

 If I take that extra line out, doesn't crash on my machine.  Will commit
 and see if it fixes the issue.
