readlink bug?

[Sam S. <sd...@gn...>]

Hi Bruno,

I observe the following behavior:

--8<---------------cut here---------------start------------->8---
$ ls -l /proc/1627/fd/
total 0
0 lrwx------ 1 sds sds 64 Mar 14 19:34 0 -> /dev/pts/23
0 l-wx------ 1 sds sds 64 Mar 14 19:34 1 -> /home/sds/src/clisp/current/build-porting64-gcc-standard_heapcodes/z
0 l-wx------ 1 sds sds 64 Mar 14 19:34 2 -> /home/sds/src/clisp/current/build-porting64-gcc-standard_heapcodes/z
0 lr-x------ 1 sds sds 64 Mar 14 19:34 3 -> /home/sds/src/clisp/current/build-porting64-gcc-standard_heapcodes/lisp.run*
0 l-wx------ 1 sds sds 64 Mar 14 19:34 4 -> /home/sds/src/clisp/current/build-porting64-gcc-standard_heapcodes/z
0 l-wx------ 1 sds sds 64 Mar 14 19:34 5 -> /home/sds/src/clisp/current/build-porting64-gcc-standard_heapcodes/z
--8<---------------cut here---------------end--------------->8---

after

GC_SAFE_SYSTEM_CALL(result = readlink(namestring_asciz,linkbuf,linklen));

(gdb) p linkbuf
$5 = "/home/sds/src/clisp/current/build-porting64-gcc-standard_heapcod\n"
(gdb) p namestring_asciz
$6 = 0x7fffffff7ff0 "/proc/1627/fd/1"
(gdb) p fs->fs_stat
$7 = {st_dev = 4, st_ino = 5336534, st_nlink = 1, st_mode = 41152, st_uid = 1001, st_gid = 1001, __pad0 = 0, st_rdev = 0, st_size = 64, st_blksize = 1024, st_blocks = 0, st_atim = {tv_sec = 1489534480, tv_nsec = 542647557}, st_mtim = {tv_sec = 1489534480, tv_nsec = 542647557}, st_ctim = {tv_sec = 1489534480, tv_nsec = 542647557}, __glibc_reserved = {0, 0, 0}}
