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: =========
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. :-)

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,

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.

This is a bug in the e2fsprogs on FC4.  Confirmed by RH developers.
Not our bug.
