[Tioga-users] Stack Smashing

[Andrew Cooper]

Hello all,

I've just installed my favourite plotting tools, Tioga 1.6 and Ctioga 
1.6.2, under Ubuntu 7.10 ('Gutsy'). The default install of Tioga seems 
to work fine (well, the tests ran OK). Ctioga's tests, however, all died 
with the following opaque statement:

*** stack smashing detected ***: ruby terminated
Aborted (core dumped)

It turns out that gcc has SSP turned on by default, as packaged 
currently in Ubuntu. See:

https://wiki.ubuntu.com/GccSsp

So I recompiled Tioga with -fno-stack-protector and the problem "went 
away", of course. I had a very brief stab at trying to figure out where 
exactly the overrun was, but with no luck. After recompiling one file at 
a time without SSP, I think the problem might be in axes.c, but that's 
as far as I got.

Hope this is of some use.

Regards,
