Hello, OK well I've tracked down the source of my problem to the operating system itself it seems.
Regardless of the versions/combinations of mapserver/gd/freetype I use, there are definite visual rendering problems when on this OS. On RedHat 7.3, everything is fine! Example: http://atlas.gc.ca/family-good.gif http://atlas.gc.ca/family-bad.gif Note the small dot that appears on the symbol? Also: http://atlas.gc.ca/the-market-good.gif http://atlas.gc.ca/the-market-bad.gif Notice how on the bad version, a bunch of point symbols are missing? I tried various combinations of: MapServer 4.6.1 and 4.8.1 FreeType 2.0.9 and 2.1.9 GD 2.0.28 and 2.0.33 A given combination works on 7.3, but not on CentOS. Without luck. The problem with the strange shape of the symbols ( http://atlas.gc.ca/mapserver-symbol-problem.png ) seemes to be related to the version of FreeType for some reason? FreeType 2.0.9 acts as we expect it to, FreeType 2.1.9 does not. There may be cumulative effects also. CentOS 4.2 uses GCC 3.4.4 and GLIBC 2.3.4. I had gotten a horrible crash message at some point with a version of mapserver on this OS (http://lists.umn.edu/cgi-bin/wa?A2=ind0602&L=mapserver-users&P=R60802&I=-3&; X=106ECE1CAE6B73E23F), but upgrading from 4.6.1 to 4.8.1 had fixed it. This was related to memory allocation. Could something related to that be causing this? Turns out I've got 4.6.1 running on this platform now, but that really didn't help. I'm out of ideas :( Anyone?
