Package: doxygen
Version: 1.9.4-4
Severity: normal
Dear maintainer,
Cairo 1.17.6 (or close to it) introduced a change[1] in how certain
PDF elements are generated which introduces a build failure in the
doxygen docs[2], as well as in other packages that use doxygen (like
fenics-dolfinx).
That version of cairo is durrently in debian experimental. As soon as
that moves to unstable, the FTBFS will start. Ubuntu is seeing it
right now[4]:

(warning treated as error, aborting now)
Segmentation fault (core dumped)

make: *** [debian/rules:125: binary] Error 2

The upstream bug report[2] had a lot of back and forth until the final
set of fixes made it into the doxygen 1.9.7 release[3]
I collected the commits, and this is the set, where some bits are even
reverted in follow-up commits:

issue #9319 Doc build fails with cairo 1.17.6
Implementing the use of the environment variable so that always
the non compressed version is written.

issue #9319 Doc build fails with cairo 1.17.6
The `\MediaBox` field is written as:
```
sscanf(p+bblen,"%d %d %d %d",&x,&y,width,height)
```
bur read with
```
sscanf(p+bblen,"%d %d %d %d",&x,&y,width,height)
```
this has been corrected.
It doesn't apply cleanly, because a big one is this, which introduces
a vendored gunzip library:

Add TinyDeflate as dependency
Maybe others are needed still, this is where I stopped. It seems safer
to update to the new upstream 1.9.7 instead, I suppose.
A short-term workaround would be to call doxygen with
CAIRO_DEBUG_PDF=1. That will tell cairo to not use compression with
those PDF elements, and then the doxygen parsing would work. Problem
is that this would have to be done for all packages that call doxygen
and are affected by this bug, and also it relies on some
cairo-specific behavior which might change.
