Bug #: 54048
Summary: Uninitialized input_location in front-end
initialization
Classification: Unclassified
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: mikael@gcc.gnu.org
Valgrind gives errors of the following kind with gfortran 4.6.3 and 4.7.1.
Can't check 4.8.0 as valgrind chokes on it (illegal instruction).

No. As far as I remember, it used to happen on any testcase, for example:
!!!
end
!!!
It seems to work now. Valgrind reports errors, but they seem to be deep down
the middle-end, and unrelated to this. Closing.
