Description Garth DAttilo 2005-06-30 13:37:10 UTC 
Using Fedora Core 4, the net ads add command fails with the following error
(followed by the usual trace):
   *** glibc detected *** net: free(): invalid pointer: 0x004d27f0
======= Backtrace: =========
/lib/libc.so.6[0x2b7424]
/lib/libc.so.6(__libc_free+0x77)[0x2b795f]
/lib/libcom_err.so.2(remove_error_table+0x4b)[0x128abb]
/usr/lib/libkrb5.so.3[0x470823]

/lib/ld-linux.so.2[0xaf2058]
/lib/libc.so.6(exit+0xc5)[0x27ec69]
/lib/libc.so.6(__libc_start_main+0xce)[0x268dee]
net[0x8e70f1]
----------------------------------------------------------------------------
It looks like the repsonse to invalid 'free()' calls has changed. 
   
   You can get around this by manually setting MALLOC_CHECK to either 0 (ignore)
or 1 (report and continue) but that's not at all obvious at the outset. :-)

Thanks,

Hmmm... Looks like that should be "net ads join"...

Comment 2 Gerald (Jerry) Carter (dead mail address) 2005-07-15 15:36:04 UTC 
any chance of getting a backtrace with debug symbols 
(compile with --enable-debug)?
Comment 3 Garth DAttilo 2005-07-25 12:59:41 UTC 
Version 3.0.20pre2 compiled with --enable-debug. Debug level set to 10.
Everything seems to progress normally until this point.
Please let me know if you want the entire log file or if I have misunderstood
what you are asking for.

Thanks in advance,
Garth

Garth,

I reproduce the same issue locally.  This looks like a 
bug in the kerberos libs which I think redhat will have to 
handle with the MIT folks.  I've copied Jay Fenlason at redaht
on this bug.
Comment 5 Gerald (Jerry) Carter (dead mail address) 2005-08-30 05:47:23 UTC 
This is a bug in the e2fsprogs on FC4.  Confirmed by RH developers.
Not our bug.
