Bug ID: 83316
Summary: ICE: minval/maxval and characters
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: physiker at toast2 dot net
Target Milestone: ---
Compiling the source file a.f90 causes an internal compiler error. I believe
the code is legal.
program tminmaxval
implicit none
character(len=*), parameter :: b = "a"
character(len=*), parameter :: e = "c"
character(len=*), parameter :: s(3) = (/"a", "b", "c"/)
if (minval(s) /= b) then
write(*,*) "minval(s) =", minval(s)
end if
if (maxval(s) /= e) then
write(*,*) "maxval(s) =", maxval(s)
end if
end program tminmaxval
