--- Begin Message ---Bram, Large values for the -c option (approximately 100 or greater) cause xxd to segfault. Where the segfault occurs seems to vary based on how large the columns option is. I get this traceback when running "xxd -b -c 100 /usr/bin/xxd". Program terminated with signal 11, Segmentation fault. #0 0xb7e6ce0d in getc () from /lib/i686/cmov/libc.so.6 (gdb) bt full #0 0xb7e4ce0d in getc () from /lib/i686/cmov/libc.so.6 No symbol table info available. #1 0x0804a0a2 in main (argc=2, argv=0xbfb6e3c0) at xxd.c:731 fp = (FILE *) 0x2e04c008 fpo = (FILE *) 0xb7f344e0 c = 16 e = 127 p = 1 relseek = 1 negseek = 0 revert = 0 cols = 100 nonzero = 1 autoskip = 0 hextype = 3 ebcdic = 0 octspergrp = 1 grplen = 9 length = -1 n = 1 seekoff = 0 l = "0000000: 01111111", ' ' <repeats 889 times> pname = 0xbfb6f984 "xxd" pp = 0xbfb6f992 "/usr/bin/xxd" #2 0xb7e01450 in __libc_start_main () from /lib/i686/cmov/libc.so.6 No symbol table info available. #3 0x08048851 in _start () No symbol table info available.
