Package: libcairo2
Version: 1.12.2-3
Severity: normal
Cairo crashes with a bus error when generating PDFs that use the font Source
Sans Pro and variants (available freely from
http://store1.adobe.com/cfusion/store/html/index.cfm?event=displayFontPackage&code=1959).
It doesn't crash with any other fonts that I have tried (although I have only
tried Liberation and Luxi), and it doesn't crash with any other output formats
(although I have only tried PNG, SVG and PostScript).
A simple test case for this is to cat the following into "dot -Tpdf":
$ dot -Tpdf
graph test {
node1 [fontname="Source Sans Pro"]
node1 -- node2
}
%PDF-1.5
