RE: [Tsp-devel] Blackboard problem !

[ZXPLECOFR004, Ext]

Hi all,


OK, I will report the bug in the tracker. Thanks for the archive. After a rapid 
test it shows that:
        - the same bug has not been reproduced
        - another bug has appeared (a freeze of bb_simu linked with the run of 
tsp_stdout_client (in 32 or 64bits))

 After rebooting the platform (due to unremovable shared memory), I have done 
the test again with 0.8.3 and it appeared that:
        - I didn't reproduced this bug with these softs (bb_simu, 
tsp_bb_provider, tsp_stdout_client)
        - The behiavour is quite strange but is different than the 0.8.4cvs 
one: It seems to do nothing

From now, Frederic will investigate on these problems. 

Any idea is welcomed !!

Olivier

Yes there may be alignment issues on using 32bits version on a 64bits hosts
however I do not expect this kind of error in this case.
In fact I think we did not try this combination, by the way how did you compile
the 32bits version? On another host? Cross-compiling 32bits on 64bits host?

0.8.3 is becoming very old, we really need to find time to release 0.8.4,
would you be able to try the CVS version? I may build you a tarball if
have no anonymous CVS access.

In any case you should open a Savannah account and report the bug in
the tracker:

I'll try that too in a day or two.
