I just tried to compile xfig from ports, and while it builds fine, it then=
=20
segfaults on startup inside libXpm.so. It goes like this:

Weirdly, adding a printf() in PutPixel32 in libXpm just makes it work - tho=
ugh=20
slowly. I've mucked about a little, changing the code in subtle ways, but i=
t=20
just keeps bailing. I get the vague feeling the compiler is falling over=20
trying to discombobulate the casts in that function.

Anyway, does anyone have a working xfig?=20
