[Bug preprocessor/15913] New: Preprocessor dies on // comment if --traditional-cpp is specified

[pkoning at equallogic dot com]

gcc -E --traditional-cpp test.c

test.c is:
#ifdef notyet
not yet
#endif // comment

Results in:
# 1 "../cvs162/NetBSD162/src/test.c"
# 1 "<built-in>"
# 1 "<command line>"
# 1 "../cvs162/NetBSD162/src/test.c"
../cvs162/NetBSD162/src/test.c:0: internal compiler error: Abort trap
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

According to gdb, the abort is in _cpp_process_line_notes.  I dug a bit and it
looks like it's processing the "sentinel" line note, which the comment says
should never be processed.  That's as far as I managed to get.
