--- Comment #12 from Rainer Orth <ro at gcc dot gnu.org> ---
The new testcase FAILs on Solaris/SPARC on trunk, gcc-7 and gcc-8 branches:
32-bit sparc:
+FAIL: gfortran.dg/unlimited_polymorphic_30.f03 -O0 execution test
+FAIL: gfortran.dg/unlimited_polymorphic_30.f03 -O1 execution test
64-bit sparc also:
+FAIL: gfortran.dg/unlimited_polymorphic_30.f03 -O2 execution test
+FAIL: gfortran.dg/unlimited_polymorphic_30.f03 -O3 -fomit-frame-pointer
-funroll-loops -fpeel-loops -ftracer -finline-functions execution test
+FAIL: gfortran.dg/unlimited_polymorphic_30.f03 -O3 -g execution test
+FAIL: gfortran.dg/unlimited_polymorphic_30.f03 -Os execution test
On gcc-testresults, there are also reports on hppa2.0w-hp-hpux11.11,
spu-unknown-elf.
The tests FAIL like this:
Program received signal SIGBUS: Access to an undefined portion of a memory
object.
Backtrace for this error:
