[Mapserver-users] Nasty bug in labelcache?

[Daniel Morissette]

If you can prepare a test case to reproduce this (i.e. small dataset and 
mapfile) with MapServer 4.2 then please submit it as a bug in bugzilla 
and we'll have a look.  Otherwise without a way to reproduce the problem 
there is not much we can do to help unfortunately.
