When did > it start triggering? I don't see the warning with 4.5.4, but I see it with 4.6.4: [macbook] f90/bug% gfortran-fsf-4.5 /opt/gcc/_clean/gcc/testsuite/gfortran.dg/warn_unused_dummy_argument_2.f90 -Wunused-parameter -c [macbook] f90/bug% gfortran-fsf-4.6 /opt/gcc/_clean/gcc/testsuite/gfortran.dg/warn_unused_dummy_argument_2.f90 -Wunused-parameter -c /opt/gcc/_clean/gcc/testsuite/gfortran.dg/warn_unused_dummy_argument_2.f90:7:0: warning: unused parameter 'dummy' [-Wunused-parameter] Compiling the test gfortran.dg/warn_unused_dummy_argument_2.f90 with -Wunused-parameter gives the ICE with 5.1/6.0. To be more precise, I dont't get the warning for 4.7 with r182107 (2011-12-08), but I get it with r182980 (2012-01-07), back ported to 4.6 between r179116 (2011-09-23) and r182981 (2012-01-07), possibly r182211 and r182213 (pr50923)
