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:

#2  0x0808508c in pp_file_change (map=0x843b030) at ../../gcc/c-ppoutput.c:384
#3  0x0807f48b in cb_file_change (pfile=0x84301f8, new_map=0x843b030) at ../../gcc/c-opts.c:1491
#4  0x080921be in cpp_change_file (pfile=0x0, reason=LC_ENTER, new_name=0x0) at ../../gcc/

#6  0x0807f452 in c_common_init () at ../../gcc/c-opts.c:1194
#7  0x08086d6e in c_objc_common_init () at ../../gcc/c-objc-common.c:166
#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.
