Please attach the problematic image as an attachment to this bug.

If you can't do that because the document is secret, then unfortunately there's little we can do for you.

There's no secret. Take it from attach.

I try this image on my Gentoo amd64 system and it segfault.
I convert image to 1-bit, after this it recognize it without segfault.

[Polevoy Dmitry (openocr-polevoy)]

I convert image to bmp with 24, 8 and 1 bit per pixel. After that my version
(Win32 + MSVC9) recognize it without any problems.
1. You can try convert image to plain 24 bpp bmp and recog it without
ImageMagic. If it fails the problem can be in 64 version.
2. You can convert image to any format with ImageMagic and if it fails, the
problem can be in ImageMagic. Some time ago I have troubles (Win32, MSVC)
with gray images in ImageMagic.

On OSX the image does not segfault, but produces empty output. Converting it to 1-bit png and recognizing that works just fine.

[Yury V. Zaytsev (zyv)]

MSVC 2008 SP1 build: works fine for 1bit PNG (converted with Gimp, but crashes for RGB and original image).

For original image:

For 32bit image, I get no crash report, but just that:

The image depth is 32 at this point.

PUMA_XFinalrecognition failed.

Fixed in my branch, rev. 938 by converting image to 24bpp via ImageMagick
