--- Comment #18 from Thomas Koenig <tkoenig at gcc dot gnu.org> --- Created attachment 46451 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=46451&action=edit Preprocessed source of library file for LTO mismatch Hi, here is a test case (preprocessed source from libgfortran). To reproduce, use the test program $ cat minloc.f90 program main real, dimension(10,10) :: a integer, dimension(2) :: m1 call random_number(a) m1 = minloc(a) print *,m1 end program main and compile/link with $ gfortran -static-libgfortran -flto -O3 minloc.f90 minloc0_4_r4.i minloc.f90:5: warning: type of '_gfortran_minloc0_4_r4' does not match original declaration [-Wlto-type-mismatch] 5 | m1 = minloc(a) | ../../../ggdb3/libgfortran/generated/minloc0_4_r4.c:38:1: note: type mismatch in parameter 3 ../../../ggdb3/libgfortran/generated/minloc0_4_r4.c:38:1: note: 'minloc0_4_r4' was previously declared here ../../../ggdb3/libgfortran/generated/minloc0_4_r4.c:38:1: note: code may be misoptimized unless '-fno-strict-aliasing' is used
