https://bugs.winehq.org/show_bug.cgi?id=38893 --- Comment #1 from Alexandre Julliard <julliard(a)winehq.org> --- RANDMMAP is not particularly useful with Wine, and will break memory reservation, but most things should still work. What is the actual problem you are seeing? -- Do not reply to this email, post in Bugzilla using the above URL to reply. You are receiving this mail because: You are watching all bug changes.

Well, i stumbled upon it when i tried to strace wine to catch what's happening with hanging Space Rangers HD. Somehow strace re-enables RANDMMAP even when it's disabled for the strace binary itself it seems. Anyway, the problem with Space Rangers is vanished somehow. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

Yes, the goal is to reserve all available memory. -- Do not reply to this email, post in Bugzilla using the above URL to reply. You are receiving this mail because: You are watching all bug changes.
