The segfault is the same problem as PR 20364, which I fixed on the gcc-3.4
branch two days ago.  The error message problem is now PR 20285.  So closing as
a duplicate.

Confirmed, here is the backtrace:
#0  0x00840a33 in strlen () from /lib/tls/libc.so.6
#1  0x08084920 in print_line (map=0x843b030, line=79, special_flags=0x0) at 
../../gcc/c-ppoutput.c:

#8  0x08275f89 in toplev_main (argc=0, argv=0x0) at ../../gcc/toplev.c:4527
#9  0x0809962e in main (argc=0, argv=0x0) at ../../gcc/main.c:35

The error message is a regression from 2.95.3, I will file a different bug for 
that.
