--- Comment #6 from Thomas Klausner <t...@giga.or.at> --- I asked the question on a NetBSD mailing list and got a reply: https://mail-index.netbsd.org/current-users/2016/11/15/msg030491.html Basically: Create a temporary file (mkstemp should make sure noone but you can read it), unlink it (to make sure nothing can happen and have automatic cleanup). Then mmap it once writable to edit the JIT code; when you're finished, mmap it execable instead. -- You are receiving this mail because: You are on the CC list for the bug. -- ## List details at https://lists.exim.org/mailman/listinfo/pcre-dev
