Odd Vector behaviour using Lambert Azimuthal Equal Area and Global Vector

[pw]

Hello,

I am working with mapserver version 4.10.1.

I am using a global polygon vector of land in SHP format.
The vector has a latlong coordinate system. The vector
has land color filled and water blank.

The map file that mapserver is using defines a map
with a Lambert Azimuthal Equal Area projection (laea).

Mapserver has no problem with the map Lambert projection
centered over most global coordinates.

PROBLEM:

I am finding that mapserver maps the land vector
inverted with land blank and water color filled when
I cross various geographic boundaries with my Lambert projection.

I have posted a map showing where Mapserver inverts the
opaque and transparent colors of the polygon vector
when using Lambert AEA.

QUESTIONS:

Is this a problem with Mapserver, GDAL, Proj4,...???
Has anyone encountered this before?
Is the problem workable or do I need another global
land vector centered on the other side of the globe?

Thanks for any info,

Peter
