[cairo] Cairo 1.8 crashes when creating PDF (OS X 10.5 PowerPC)

[Asko Kauppi]

If you add 'cairo_show_text()' to the mix, the crash is there.

This one gives "Bus error", other circumstances can give "Segmentation  
fault".  Most likely it's the same issue, though (always within  
'cairo_show_text()'.

$ gcc `pkg-config cairo --cflags --libs` -o testme_c testme.c
$ ./testme_c
