ImageMagick: "convert" segfaults on pdf->eps conversion

$ convert mp.pdf mp.eps
Segmentation fault

This happens on every pdf conversion I've tried (pdf->eps or jpg or tiff or gif). Other conversions appear to work OK.

I took a quick look through the ImageMagick bugs and users lists and didn't see anything relevant, so this might be a MacPort-specific problem. It'd be nice if someone else could try to reproduce. I did not see this behavior before, but don't use convert a lot.

I am attaching a png and pdf (convert png->pdf). Converting the pdf to eps segfaults for me.

I can confirm that anything I tried with PDFs leads to a segmentation fault (identify, convert, display).

Seems to work for me (10.5.8, Xcode 3.1.3, Intel), I do note that my convert does not report OpenMP, could that be related?

$ port installed ImageMagick

I had no problem under 10.5.8 neither, it's just happening since 10.6. Don't know where the OpenMP comes from, I didn't see an option for that.

The request to add OpenMP support is still outstanding, but I'm guessing ImageMagick automatically enables it if GCC is new enough, and presumably GCC on Snow Leopard is new enough.

Cc Me!

I see the problem too, but will just be reporting it to the magick-bugs list, once I confirm the problem still exists in the latest release (6.5.5-7).

[ryandesign@…]

6.5.5-7 works for me. Can you "sudo port selfupdate" and "sudo port upgrade ImageMagick" and see if it works for you too?

[codex69@…]

Works for me, too!
