Hi,
I've recently uploaded libcgns 8.4.0-1~exp1 to experimental. All builds but
ppc64el are ok.
The ppc64el failure [0] occurs in the test suite (test cgread_f03), when a C
va_arg function (src/cg_ftoc.c:cg_goto_f()) is called from Fortran code
(src/tests/cgread_f03.F90:421). This function is called several times. Is is
successful at first, then it fails badly because the corresponding hidden
string length parameters[1] are equal to 0. This shouldn't happen because the
related strings are literals: 'Zone_t', 'GridCoordinates_t', 'end'.

[1] https://gcc.gnu.org/onlinedocs/gfortran/Argument-passing-conventions.html
Further investigation shows that release 3.3.0-6 of libcgns FTBFS the very same
way with GCC 8.3.0, while it succeeded with GCC 8.2.0 [2].

I then ran a bisect on the GCC svn branch 'gcc-8-branch' and found out that the
failure was introduced by the r269349 changeset [3].

This is a backport of the trunk r268992 changetset [4] introduced during GCC-9
development.

At this point I don't know where to go. I'm setting severity = serious because
this change now present into Debian/sid GCC-{7,8,9} makes libcgns FTBFS on
ppc64el. Feel free to downgrade it if you think it appropriate.
Any help appreciated. Many thanks in advance,
_g.
