Hello, I found the package FTBFS on Ubuntu, checked on amdahl and found the
same issue.

Full log attached
Thanks for this bug report. I can indeed reproduce the problem.
It was triggered by the recent change in dpkg-buildflags, which now
includes -fstack-clash-protection in FFLAGS. This was done through commit
1d46b351f [1], , intended to fix Bug#1054583 [2], and which got included
in version 1.22.1 of dpkg-dev, released on October 30.
The Fortran example x09f.f90, which is exercised during the building of
plplot, now fails on armhf, due to the use of the compiler option
-fstack-clash-protection. I did not check whether this is also the case
for arm64 and armel.
As far as I can tell, this is due to a global variable (tr) that is not
correctly accessed in a private function (mypltr) of the x09f program.
There may be a programming error in x09f.f90 or this may be a problem
with gfortran on armhf. My knowledge of Fortran is almost non existent
and I will need the help of experts, in order to fix the issue.
Best,
Rafael Laboissière
