valgrind logs
Hi,
>From https://bugs.debian.org/854194
Valgrind 3.12.0 segfaults when I try to run anything on a Cavium Octeon board.
I've tried both Octeon II and Octeon III boards. It seems to be hardware
specific, because valgrind does work on the CI20 and on Loongson boards (after
hacking /proc/cpuinfo a bit).
The behavior changes when I modify the environment. Changing the environment
changes where the segfault occurs (ie the last SB reported). If I run valgrind
after the environment is cleared with env -i, it doesn't segfault and instead
hangs, although I think this is Bug 344524. On Octeon II it completes.
I've attached two examples run on an Octeon III machine.
