Bug ID: 92027 Summary: [10 regression] gfortran.dg/ISO_Fortran_binding_10.f90 FAILs Product: gcc Version: 10.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: libfortran Assignee: unassigned at gcc dot gnu.org Reporter: ro at gcc dot gnu.org Target Milestone: --- Target: sparc-sun-solaris2.11, m68k-*-*, powerpc*-*-* Between 20191004 (r276564) and 20191005 (r276629), a fortran testcase regressed: +FAIL: gfortran.dg/ISO_Fortran_binding_10.f90 -O2 execution test +FAIL: gfortran.dg/ISO_Fortran_binding_10.f90 -O3 -fomit-frame-pointer -funroll-loops -fpeel-loops -ftracer -finline-functions execution test +FAIL: gfortran.dg/ISO_Fortran_binding_10.f90 -O3 -g execution test +FAIL: gfortran.dg/ISO_Fortran_binding_10.f90 -Os execution test I'm seeing it on Solaris/SPARC (64-bit only), but there are also reports on m68k and powerpc*. If I use the unmodified executable with libgfortran.so from GCC 9, the test PASSes. The failure (at -O2) is as follows: FAIL 5: 11.0000000 13.0000000 15.0000000 STOP 4
