Hi, I don't how to start and if this is useful at all.
On my ppc G4 gentoo, I have problem with cairo for month now since 1.10.
At the beginning of may 2011, I tried with the git HEAD and it gave me back
thunderbird and firefox. But then I had to upgrade for Qt upgrade to 4.8 but
this brought crashes.

So, I tried running tests to see what I could find.
They give a lot of crashes, so many that I am not sure this report can be
useful as it looks like I have a very cranky system (but KDE-4.6.5 is run quite
fine on it). Some are assert failures, some are not.

Launching : make run TOOL=gdb
gives me a crash :

gcc is 4.5.3

By the way, how can I get an unoptimized-out test binary ?

Thanks in advance.
