Reproducible: Always Steps to Reproduce: 1. create file (not empty) with long name, say bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb 2. share it on ftp server 3. try 'du bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb' in lftp 4. lftp segfaults (checked on remote serwer and localhost) 5. it also happens if path is very long e.g. bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb/bbbbbbbbbb Actual Results: gdb bt full #0 0x000000327e476c10 in strlen () from /lib/libc.so.6 No symbol table info available. #1 0x000000327e445e10 in vfprintf () from /lib/libc.so.6 No symbol table info available. #2 0x000000327e4697fa in vsnprintf () from /lib/libc.so.6 No symbol table info available. #3 0x00002b9562760c17 in Buffer::vFormat (this=0x6139d0, f=0x2b956251ebc8 "%s\t%s\n", v=0x7fff485e1eb0) at buffer.cc:158 tmp = {{gp_offset = 32, fp_offset = 48, overflow_arg_area = 0x7fff485e1f90, reg_save_area = 0x7fff485e1ed0}} res = <value optimized out> size = 1649535944 #4 0x00002b9562760cdc in Buffer::Format (this=0x9, f=0x2b956251ebc8 "%s\t%s\n") at buffer.cc:147 v = {{gp_offset = 40, fp_offset = 48, overflow_arg_area = 0x7fff485e1f90, reg_save_area = 0x7fff485e1ed0}} #5 0x00002b9562514bc0 in FinderJob_Du::print_size (this=0x6694e0, n_blocks=<value optimized out>, string=0x687d90 'b' <repeats 64 times>) at FindJobDu.cc:177 buffer = "\n\000\000\000\000\000\000\0008zf\000\000\000\000\000\001\000\000\000\000\000\000\000\024\000\000\000\000\000\000\000=É\r\215\000\000\000\000L\216\000~2\000\000\000\002\000\000\000\000\000\000\000\234SNb\225+\000\000Zìm\020\000\000\000\000L\216\000~=\000\000\000$74\002\000\000\000\000\000 ^Hÿ\177\000\000h!^Hÿ\177\000\000ø[Nb\225+", '\0' <repeats 18 times>, "ØPLb\225+\000\000rþNb\225+\000\000p³Nb\225+\000\000H\201Nb\225+\000\000\000\000\000\000\001\000\000\000\216\001\000\000\001\000\000\0008tsb\225+\000\0000TLb\225+\000\000 !^Hÿ\177\000\000P!^Hÿ\177\000\000"... #6 0x00002b9562514d1b in FinderJob_Du::ProcessFile (this=0x6694e0, d=<value optimized out>, fi=0x688170) at FindJobDu.cc:141 add = <value optimized out> #7 0x00002b95625133c1 in FinderJob::Do (this=0x6694e0) at FindJob.cc:144 m = 1 pres = <value optimized out> j = <value optimized out> #8 0x00002b956274c46e in SMTask::Schedule () at SMTask.cc:226 scan = (SMTask *) 0x6694e0 timer_timeout = <value optimized out> res = 0 #9 0x00002b95624fc9b2 in Job::WaitDone (this=0x6136d0) at Job.cc:522 No locals. #10 0x0000000000405be8 in main (argc=1, argv=0x7fff485e2418) at lftp.cc:466 home = <value optimized out> exit_code = <value optimized out> #11 0x000000327e41e1f4 in __libc_start_main () from /lib/libc.so.6 No symbol table info available. #12 0x0000000000405239 in _start () No symbol table info available.
