Is there any reason why valgrind 3.6.1 doesn't work for you? I is possible for me to backport the linux 3.x patch to 3.5, but I don't see a point if 3.6 is working.

So summarizing: * 3.6.1 does not compile, * 3.6.1-r1 does compile but fails with "unhandled DW_OP_ opcode 0x2a" (for a full description, see the first comment). The bugzilla upstream offers this patch http://bugsfiles.kde.org/attachment.cgi?id=61618 which was committed to their svn. See comments 5 and 6 at https://bugs.kde.org/show_bug.cgi?id=277045#c5

See comments 5 and 6 at https://bugs.kde.org/show_bug.cgi?id=277045#c5 Sorry for the confusion, I see the issue now. Please test valgrind-3.6.1-r3. It includes upstream commits r11856 and r11904.
