On building a stock ImageMagick 4.2.8 distribution on NetBSD 1.4/i386
(not via pkgsrc, I actually didn't even look if it's in there) the
archiver ar(1) is invoked to create libMagick.a.
It never completes this, since it is killed via SIGSEGV before:

I wanted to compile ar with debugging infos but found out that with the
Gnu binutils tree, compiling a single tool is a little difficult; whatever,
I didn't have the time to dive into it, a quick attempt at configuring
and compiling it failed.  I would be thankful if some kind soul gave me
a hint on how to compile only ar(1) with sufficient debugging info for
identifying the bug in the source without having to compile the entire
binutils subtree.

Obtain ImageMagick-4.2.8, untar and build.
None known to me.
