Errors at installing rgdal on Debian Buster

The problem seems to be related to the compiler. I had:
gcc version 5.3.1 20160101 (Debian 5.3.1-5)

I have now:
gcc version 7.2.0 (Debian 7.2.0-4)

All weird previus errors are gone but I still have:
configure: PROJ.4 version: 4.8.0
./configure: line 3725:  8390 Segmentation fault      ./proj_conf_test
checking PROJ.4: epsg found and readable... yes
./configure: line 3800:  8399 Segmentation fault      ./proj_conf_test

and finally

** testing if installed package can be loaded
Fatal error: glibc detected an invalid stdio handle
Aborted
ERROR: loading failed
* removing ?/home/alobo/R/i686-pc-linux-gnu-library/3.3/rgdal?

Surprisingly,  I do have 4.9 installed, not 4.8:

$ dpkg -s proj-bin
Package: proj-bin
Status: install ok installed
Priority: optional
Section: science
Installed-Size: 125
Maintainer: Debian GIS Project <pkg-grass-devel at lists.alioth.debian.org>
Architecture: i386
Source: proj
Version: 4.9.3-2

and
$ proj
Rel. 4.9.3, 15 August 2016
usage: proj [ -bCeEfiIlormsStTvVwW [args] ] [ +opts[=arg] ] [ files ]

and I cannot find proj_conf_test anywhere:
$ sudo find / -name 'proj_conf_test'
gives no result

How is the test ./proj_conf_test done so that I can investigate why it
results into PROJ 4.8 instead of 4.9?

Thanks

$ g++ -v
...
gcc version 7.1.1 20170622 (Red Hat 7.1.1-3) (GCC)

in my case on Fedora 26.

Recent versions should be OK, but < 5 may be problematic. If you have
upgraded in place but not upgraded the compile trains, installing r-base
will not force that.
