Giffuni changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |pfg@FreeBSD.org --- Comment #16 from Pedro F. Giffuni --- (In reply to Ed Maste from comment #0) For the record, in the recent "Rethinking the Stack Clash fix" LWN article, there are some claims that on i386 linux the stack guard may cause issues f= or LibreOffice. Quoting the relevant part of the article: "That guard region should be invisible to most programs, but it has created= a surprising number of problems for some applications. A number of those issu= es have been worked around, but one has proved difficult to fix; unfortunately, that one is LibreOffice, which can crash on 32-bit systems when running Java components. The issue is a bit complicated but, in short, Java wants to ena= ble code execution in memory located immediately below the stack, which runs af= oul of the guard region." --=20 You are receiving this mail because: You are on the CC list for the bug.=
