ghostscript @9.05_0 missing characters in loaded fonts

[rosgen@…]

Since upgrading ghostscript to @9.05_0 certain characters in postscript and pdf files are not displayed. Reverting to @9.04_1 fixes the problem.

This is on a system running 10.6.8. Potentially relevant ports installed are:

freetype @2.4.9_1+universal
fontconfig @2.9.0_1+universal

The problem occurs on the attached pdf file (and on other files). The text in the left margin is missing several characters. I've attached two screenshots: the behaviour in 0.94_1.png is the correct behaviour displayed by ghostscript @9.04_1, while the behaviour shown in 0.95_0.png is what ghostscript @9.05_0 displays. Other pdf viewers agree with the output of @9.04_1.

The console output of @9.05_0 on this file is:

Whereas in @9.04_1 the output is:

The only differences are in the numbers displayed regarding the loaded font. It seems like the font is either corrupt or being loaded incorrectly.

I guess this is because the latest freetype is broken.

I could reproduce your bug using the latest ghostscript (@9.05) and freetype (@2.4.9_1) easily. But when I downgrated freetype to @2.4.8_0, the problem was gone.

Reverting to @9.04_1 fixes the problem.

ghostscript @9.04_1 uses its own freetype library. (i.e. it doesn't depend on MacPorts' freetype library.) So, the problem doesn't occur even if MacPorts' freetype library is broken..
