I can reproduce on all platforms.
Which gd library do you use with your extension linux? Bundled or
external? If external, which version on which linux?
The bug seems to be in the polygon function, the clipping looks like
the cause.
What you are looking (as a "work 'round") may be:
imagefilledarc($im,$corRad, 399-$corRad, $corRad*2,$corRad*2, 90, 180,
$arcFillColor, IMG_ARC_PIE);
As the actual postion of the last line is 399, not 400. But the bug is
valid > assigned.
