convert crashed with SIGSEGV in WriteImage()

[Adam Buchbinder]

Binary package hint: imagemagick

I was testing bug 37510 to see if it's still present in Intrepid; it crashes now instead of giving incorrect output. Since it works properly if I turn off verbose mode, I'm considering this a new bug.

Attached find the input file used in the command "convert -verbose small-test.psd small-test-tmp%d.tif". The PSD is a layered file.

The crash only occurs when the -verbose flag is specified; otherwise, it works properly and produces the correct output.

Just to be explicit about it, the following command produces the crash:

$ convert -verbose small-test.psd small-test-tmp%d.tif

The following command does not crash:

$ convert small-test.psd small-test-tmp%d.tif

The bug is present in upstream SVN as of today (r13567). I've reported the bug on the ImageMagick forums:

The ImageMagick developers have been able to reproduce the bug, and are working on a fix.

Any news of the upstream status ?
