Yes, it looks assertion-like.  Here is what I found in the gdal source
code, at line 405 of cpl_conv.cpp

void CPLVerifyConfiguration()
{
/* -------------------------------------------------------------------- */
/*      Verify data types.                                              */
/* -------------------------------------------------------------------- */
    CPLAssert( sizeof(GInt32) == 4 );
    CPLAssert( sizeof(GInt16) == 2 );
    CPLAssert( sizeof(GByte) == 1 );

    if( sizeof(GInt32) != 4 )
        CPLError( CE_Fatal, CPLE_AppDefined,
                  "sizeof(GInt32) == %d ... yow!\n",
                  sizeof(GInt32) );

/* -------------------------------------------------------------------- */
/*      Verify byte order                                               */
/* -------------------------------------------------------------------- */
    GInt32   nTest;

    nTest = 1;

#ifdef CPL_LSB
    if( ((GByte *) &nTest)[0] != 1 )
#endif
#ifdef CPL_MSB
    if( ((GByte *) &nTest)[3] != 1 )
#endif
        CPLError( CE_Fatal, CPLE_AppDefined,
                  "CPLVerifyConfiguration(): byte order set wrong.\n" );
}

Oops.  Here's the libraries related to gdal and mapserver:

  mapserver  4.4.1
  gdal       1.1.9_1
  jpeg       6b_0
  libgeotiff 1.2.1_0
  libpng     1.2.8_1
  proj       4.4.7_0
  tiff       3.7.1_0
  zlib       1.2.2_1

It seems odd that this hasn't been hit before.  So, I'm suspicious now
of how gdal was built.  :-/  Is there a good way to test gdal?

Thanks for the help, Sean.
