On what version of valgrind were you seeing this problem? The patch you reference above was a patch I developed and attached to a bug I opened -- https://bugs.kde.org/show_bug.cgi?id=259977. But that patch was not accepted. Julian proposed an alternative solution, which I verified as acceptable, and that's what was committed upstream. You should try an upstream snapshot and make sure that works for you. -Maynard > > > -----Original Message----- > From: John Reiser [mailto:jrei...@bitwagon.com] > Sent: 2011年6月29日 10:37 > To: valgrind-users@lists.sourceforge.net > Subject: Re: [Valgrind-users] Segmentation fault on ppc > >> I managed to cross-compile valgrind for linux on ppc (MPC8313), but >> failed to run it.
