--- Comment #2 from Gerhard Steinmetz <gerhard.steinmetz.fort...@t-online.de> --- Test case from comment 0 can be reduced to e.g. $ cat z3.f90 program p real, parameter :: w(2) = [real :: 0, 3.0*[real :: 2]] print *, w end program $ gfortran-6 -c z3.f90 f951: internal compiler error: Segmentation fault Another variation is to revers operands. As known, this compiles and runs, but gives WRONG results. $ cat z4.f90 program p real, parameter :: w(2) = [real :: 0, [real :: 2]*3.0] print *, w end program $ gfortran-6 z4.f90 $ a.out 0.00000000 0.00000000 Analogous for other operations, other intrinsic types, other combinations - look up especially in attached files of pr66193. Some variants segfault, some compile and run silently wrong. This theme is known from pr66193.
