File 0001-Fix-crash-when-running-QtCore-Stack-is-misaligned-on.patch of Package libqt5-qtbase.31637
From c6971637a9fc900de67966e7222337f0cb88106b Mon Sep 17 00:00:00 2001 From: Thiago Macieira <thiago.macieira@intel.com> Date: Wed, 2 Oct 2019 07:56:16 -0700 Subject: [PATCH] Fix crash when running QtCore: Stack is misaligned on x86-64 When our ELF entry point function is started by the kernel, the stack is aligned at 16 bytes. However, the stack is expected to be off by 8, due to a preceding CALL instruction which didn't exist. This cauases a crash further down as the compiler may generate aligned stack access.
