From: Mikolaj Kucharski Subject: mupdf-1.28.2 SIGSEGV, cannot reproduce, 8.0-beta To: ports@openbsd.org Date: Sun, 30 Aug 2026 07:27:17 +0000 Hi. MuPDF crashed on me, but not sure how I triggered it, as I cannot repro now. It was an invoice, but reopening it again multiple times worked fine. It was once off. Sending to the list, for the records. As this is not that fresh -current I will upgrade soon. $ sysctl -n kern.version OpenBSD 8.0-beta (GENERIC.MP) #92: Sun Aug 16 11:10:06 MDT 2026 deraadt@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP $ ls -1 /var/db/pkg/ | grep mupdf mupdf-1.28.2 $ egdb -quiet -batch -x gdb-commands.txt -e /usr/local/bin/mupdf-x11 -c mupdf-x11.core [New process 414008] Core was generated by `mupdf-x11'.
