Hmmm.  I just tried a test with the old version of gd.c, and all the
segfaults go away.  With the new gd.c I also overrode GD2_VERS to be 1 and
the result was no segfaults.  However, if I left it at 2 (i.e., actually
compile your 3 calls to gdImageSetThickness(dev->im_out, pls->width)), the
segfaults come back.  Either there is something wrong with libgd 2.0.1 or more
likely dev->im_out or pls->width are not properly set when you make these
calls. (Recall our previous Linux segfault problem with gd was caused by a
subtle undefined argument problem.)

Until you can find the answer, I have overriden GD2_VERS in the interest of
keeping -dev png operational on CVS head.
