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.
