--- Comment #19 from Rainer Orth <ro at gcc dot gnu.org> ---
The new gfortran.dg/promotion_4.f90 test FAILs on sparc-sun-solaris2.11:

+FAIL: gfortran.dg/promotion_4.f90   -O0  (test for excess errors)
+WARNING: gfortran.dg/promotion_4.f90   -O0  compilation failed to produce
executable

32 and 64-bit at all optimization levels:

Excess errors:
f951: Fatal Error: REAL(KIND=10) is not available for '-fdefault-real-10'
option
compilation terminated.

According to gcc-testresults, there are failures on aarch64-unknown-linux-gnu,
powerpc64le-unknown-linux-gnu, s390x-ibm-linux-gnu, and m68k-unknown-linux-gnu.
