--- Comment #1 from Uli Schlachter <psychon at znc.in> ---
Well, what do you want me to do with this report? The C program you link to
"just" renders SVGs and the SVG files which you claim to attach aren't
attached. Just saying that somewhere there is a use of undefined variable that
causes malfunction in cairo doesn't really help me.

And yes, you say that you will attach the files after the bug was marked
private. Sadly I don't think I have more rights in bugzilla than you do. And,
as far as I know, firefox bundles their own (ancient?) copy of cairo anyway, so
having a fixed cairo version won't help firefox immediately anyway.

I can see why you don't want to provide the SVG files. How about a list of
uninitialized variables? (With git commit id, file name, line, or something
like that) Or alternatively a patch which initializes these variables? (That
should turn this problem into NULL pointer dereferences which should be "less
severe" and unitialized variables should be easy to initialize to NULL / 0 /
0.0 / whatever)
