[Bug c/20239] New: ICE on empty preprocessed input

["lalle at sics dot se" <gcc-bugzilla at gcc dot gnu dot org>]

When feeding a preprocessed input file consisting of only a newline to gcc, it
gets a segmentation fault:

snaga:tmp> rm -f test.i
snaga:tmp> echo > test.i
snaga:tmp> gcc test.i
test.i:1: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
