[Bug fortran/32813] New: [4.3 Regression] ICE for array expression in empty if statement, compiled with -fbounds-check

[jaydub66 at gmail dot com]

I get an ICE when compiling the following code with the -fbounds-check option:


program emptyif

  implicit none
  integer i,K(4)

  if (K(i)==0) then
    ! do absolutely nothing
  end if

end program


the error message is:

emptyif.f90: In function ‘MAIN__’:
emptyif.f90:6: internal compiler error: in annotate_all_with_locus, at
gimplify.c:806

this error only occurs under the following circumstances:
* GCC version 4.3 (4.1 and 4.2 work)
* compilation with -fbounds-check option
* if statement is "empty" (contains no further statements/does nothing)
* an array expression is involved

I noticed this bug in rev. 126726 and I suspect it's a relatively new
regression, probably introduced during the last week (or two), because I think
around July 9 I was still able to compile code like the above without errors.
