[cairo] Anyone interested in fuzzing issues?

[Albert Astals Cid]

We recently added fuzzing to the cairo renderer in poppler and we're getting quite some issues like

==937==ERROR: AddressSanitizer: SEGV on unknown address 0x621ffffffbf1 (pc 0x00000128668c bp 0x7fff021c0130 sp 0x7fff021c0130 T0)

Anyone interested in the full traces/files to reproduce those issues?

Cheers,
