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 ??

(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: http://www.freebsd.org/cgi/query-pr.cgi?pr=59552 Can someone, please, comment? -mi
