Looks like a segmentation fault. To debug this, I'd have to see a GDB backtrace and/or Valgrind output. To generate the latter something like this should work: valgrind --tool=memcheck --num-callers=100 perl t/CairoSurface.t

done (first attachment); and based on output, valgrind-full is with the --leak-check=full call

Oh, you haven't actually installed the module. In that case you'll need to tell perl where to find it: valgrind --tool=memcheck --num-callers=100 perl -Mblib t/CairoSurface.t

Yeah... had it installed, but was afraid that the library in the existing path might be skewing the results so I uninstalled it (was installed without passing tests btw). Attached are the valgrind outputs as requested, thanks!

Hmm. If I had to guess, I'd say it's a problem in libcairo itself. Can you get a backtrace and/or valgrind log with a libcairo with debugging symbols?

Hope this helps - rebuilt libcairo (and version bumped) with debug symbols enabled, but I'm horrible at this level of debugging, so if anything is missing let me know. Thanks! (I'm not afraid to recompile parts with debugging enabled if it helps - but fwiw, i'm not the only one failing on this test :/) Program received signal SIGSEGV, Segmentation fault.

OK, I can reproduce this now. I think it's a cairo issue: <http://lists.freedesktop.org/archives/cairo/2007-May/010546.html> No response yet, unfortunately.

On the upside, at least I'm not insane :)

I've just released Cairo 1.040 which simply skips the troublesome tests for now.
