Here is the dpatch version (thanks to
http://matrixhasu.altervista.org/?view=use_dpatch).
Raphaël do you have the time to produce a 1.3+dfsg-4.8 ?
Thanks,

I can find some time to do it and release a revision to the DSA

With this patch added and segfault1.dpatch removed, OpenSlide
successfully decodes
Just for reference, I was given by geissert@d.o the input files to
reproduce the segfault.
segfaul1.dpatch work around issue as demonstrated in:

Of course

As per upstream commit, I think the gulty patch could be safely exchanged with:

Indeed
p0_06.j2k is part of the conformance test suite and successful decoding of
it is mandatory to stay compliant with standard.

Antonin,
As per:
http://bugs.debian.org/734238#17
It seems the code in openjpeg assume that all components have at
least the number of blocks of the first component, hence a patch has
been applied as:
http://patch-tracker.debian.org/patch/series/view/openjpeg/1.3+dfsg-4.7/segfault1.dpatch
Hi,
For further reference, this is the change made with segfault1.dpatch
I'm not sure how it is that openjpeg even works with that image, as
there are some parts of the code that really assume that all
components have at least the number of blocks of the first component.
Possibly making it write
The slide file at [1] contains 4,569 chroma-subsampled J2K images, and
the file at [2] contains 25,120. The below program will decode every
image into memory via OpenSlide. It executes Valgrind-clean against
both slides on 1.3+dfsg-4.6.
The functionality does work, and people use it.
