Hi Thibaut,

thanks a lot for the pointer to a potential solution of the problem.

I tried to find the essential change of this patch ignoring all
autogenerated files I considered (possibly wrongly) the follwing
patch:

     https://anonscm.debian.org/viewvc/debian-med/trunk/packages/R/r-cran-treescape/trunk/debian/patches/0001-fixing-issue-with-new-release-of-ape.patch?view=markup

I uploaded the package including the patch but the problematic build
issue remains.  While I admit that I have no idea about R internals
nor what ape is doing I somehow can not understand in how far the
error:

...
** preparing package for lazy loading
Creating a generic function for 'toJSON' from package 'jsonlite' in package 'googleVis'
Warning in rgl.init(initValue, onlyNULL) :
  RGL: unable to open X11 display
Warning: 'rgl_init' failed, running with rgl.useNULL = TRUE
Error: segfault from C stack overflow
* removing '/«PKGBUILDDIR»/debian/r-cran-treescape/usr/lib/R/site-library/treescape'
...

should be related.  The full build log is available online

  https://buildd.debian.org/status/fetch.php?pkg=r-cran-treescape&arch=i386&ver=1.10.17-2&stamp=1481212918

the critical part is quite at the end.

Kind regards

     Andreas.
