Has anyone had any luck using ImageMagick built with modules support?

If I try that, and follow-up with `gmake check' (in the ${WRKSRC}),
about a fifth of ImageMagick's own self-tests seg-fault -- all of
them inside __cxa_finalize (after main() has already returned):

	mi@aldan:ImageMagick/work/ImageMagick-6.3.5 (1023) gdb tests/.libs/rwblob tests/rwblob.core
	[...]
	(gdb) where 5
	#0  0x0000000804008cc0 in ?? ()
	#1  0x00000008020079e2 in __cxa_finalize () from /lib/libc.so.6
	#2  0x0000000802007637 in exit () from /lib/libc.so.6
	#3  0x0000000000401135 in _start ()
	#4  0x000000080052a000 in ?? ()
	(More stack frames follow...)
	(gdb)
	mi@aldan:ImageMagick/work/ImageMagick-6.3.5 (1024) gdb tests/.libs/rwfile  tests/rwfile.core 
	[...]
	(gdb) where 5
	#0  0x0000000803f04cc0 in ?? ()
	#1  0x00000008020079e2 in __cxa_finalize () from /lib/libc.so.6
	#2  0x0000000802007637 in exit () from /lib/libc.so.6

	#4  0x000000080052a000 in ?? ()
	(More stack frames follow...)
	(gdb) 

Full build/test log can be seen here:

	http://aldan.algebra.com/~mi/IM-6.3.5-3.failure.log

Building without modules (as is the port's default) allows all self-tests to
pass smoothly.

According to ImageMagick and GraphicsMagick developers, these crashes are due
to some "reckless" calls to atexit() from inside the modules (or inside the
modules-loaded graphics librarires). By the time the program is exiting, the
libraries with the atexit-loaded functions may already be unloaded.

But I thought, FreeBSD had that case covered since 2003:

Can someone, please, comment?
