When compiling the following code with current gfortran 4.3, the compiler ICEs module test contains function gn_lc2uc1(string_lc) result(string_uc) character(len = *), intent(in) :: string_lc character(len = len(string_lc)) :: string_uc integer :: ch, nch, i logical :: found nch = len(string_lc) found = .false. do ch = 1, nch i = ichar(string_lc(ch: ch)) if (((i >= 97) .and. (i <= 122)) .and. (.not. found)) then string_uc(ch: ch) = char(i - 32) found = .true. else if ((i >= 65) .and. (i <= 92)) then string_uc(ch: ch) = char(i) found = .true. else string_uc(ch: ch) = char(i) end if end do end function gn_lc2uc1 end module test martin@linux:~/tmp> gfortran -O2 -v test.f90 Driving: gfortran -O2 -v test.f90 -lgfortranbegin -lgfortran -lm -shared-libgcc Using built-in specs.

See <URL:http://gcc.gnu.org/bugs.html> for instructions. The ICE does not occur with the head ov the 4.2 branch, so the probelm must be very new. It does not appear at lower optimisation levels either.
