[Valgrind-developers] Valgrind and PPC

[Bart V. A. <bar...@gm...>]

Since yesterday I see new assertion failures appear on PPC with trunk
r10399 with many regression tests. These are probably related to
recent core changes. Julian or Nick, can one of you have a look at
this ?

Note: see also the FAQ in the source distribution.
It contains workarounds to several common problems.
In particular, if Valgrind aborted or crashed after
identifying problems in your program, there's a good chance
that fixing those problems will prevent Valgrind aborting or
crashing, especially if it happened in m_mallocfree.c.

If that doesn't help, please report this bug to: www.valgrind.org

In the bug report, send all the above text, the valgrind
version, and what OS and version you are using.  Thanks.
