[cairo] Getting SIGSEGV in pixman

[Hakki Dogusan]

Hi,

(WinXP, MinGW (gcc-4.6.2), Cairo-1.12.2, Pixman-0.25.2)

My program runs successfully with Cairo-1.10.2, but getting SIGSEGV with 
1.12.2.

Back trace is as follows:

Debugger name and version: GNU gdb (GDB) 7.4
Program received signal SIGSEGV, Segmentation fault.
