#498: Alignment test is unreliable on linux due to unaligned access fixups in
kernel
----------------------+-----------------------------------------------------
Reporter: ccollins | Type: bug
Status: new | Priority: normal
Milestone: | Component: configure
Version: 1.0.0 | Severity: low
Keywords: | Lang:
Patch: new | Platform: linux
----------------------+-----------------------------------------------------
On ia64, alpha and a number of other archs, the Linux kernel installs a
unaligned access fixup handler which hides unaligned accesses from
userspace tasks. There is still a significant performance hit however.
Attached patch fixes the test under linux by disabling the fixup handler
for that test if prctl() is available.
