>Description:
A core dump is issued if you execute the 'tee' command with a
file that exists but you have no permission to write to it.
>How-To-Repeat:
$ su -
$ touch /tmp/core.lst
$ su - anyotheruser
$ mysql -u <anyotheruser> -p <dbname>
mysql> tee /tmp/core.lst
>Fix:
gdb tells me the stack trace is:
#0 0x401860cf in _IO_vfprintf (s=0x0, format=0x806a873 "Logging to file
'%s'\n", ap=0xbffff7a8) at vfprintf.c:270
#1 0x8054113 in tee_fprintf ()
#2 0x80530b7 in com_tee ()
#3 0x805134f in read_lines ()
#4 0x80509be in main ()
#5 0x4014eb65 in __libc_start_main (main=0x805068c <main>, argc=3,
ubp_av=0xbffffac4, init=0x804fba8 <_init>, fini=0x80687fc <_fini>,
rtld_fini=0x4000df24 <_dl_fini>, stack_end=0xbffffabc) at
../sysdeps/generic/libc-start.c:111
Therefore, the problem is likely to be in tee_fprintf().
