[Octave-bug-tracker] [bug #30478] prelinking causes octave to crash

[John Hunt]

Follow-up Comment #7, bug #30478 (project octave):

Related reproducible crash, with octave 3.2.4, 3.3.52 and 
3.3.52+ development version 
(hg clone http://www.octave.org/hg/octave)

on OpenSUSE 11.3, 64bits 
uname -a :
Linux xxxx 2.6.34.7-0.3-desktop #1 SMP PREEMPT 2010-09-20 15:27:38 +0200
x86_64 x86_64 x86_64 GNU/Linux


removing preload functionnality
sudo zypper rm preload
and the crash disappeared

bringing it back
sudo zypper install preload
and the crash is back also


Procedure to generate the crash (order matters):
open two terminals, and type

    Terminal 1                Terminal 2
1)  octave
2)  exit
3)  octave
4)  exit
5)  octave
6)                              octave
7)  exit
8)                              exit
9)  octave
10)                             octave=>Segmentation fault

the crash looks like that:
$ octave
Segmentation fault
$

Sometimes it does not crash (due to a different initial state ?),
but after the first SegFault on terminal 2, just exit from octave
in terminal 1, and starting again the procedure the crash always
occurs, either always at step 6 or always at step 10 (again
depending on initial conditions ?)

At the identified crashing step, 
replacing the command octave by gdb octave, 
and typing run, gives no crash at all.
