Bug ID: 59024
Summary: ICE: after printing certain error messages, the
compiler seg faults.
Product: gcc
Version: 4.8.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: kimwooyoung at gmail dot com
This reproducer causes the compiler to seg fault.
The compiler exits normally with the commented-out version.
The reproducer is not a legal fortran program, but the compiler should not die
with a seg fault.
