I'll explain the problem: On ppc32 & ppc64 valgrind needs to redirect the highly optimized strlen in ld*.so, because otherwise it will result in so many false positives that the results are unusable. If ld is stripped (and splitdebug is not in FEATURES I guess) then valgrind cannot find strlen and will refuse to run altogether. So basically, valgrind cannot be used on ppc if ld has been stripped. vapier@gentoo.org 2008-03-23 16:21:00 0000 sounds like you already have a solution: stick a warning into the ebuild. i'd say the warning valgrind already emits is sufficient: valgrind: Possible fix: install glibc's debuginfo package on this machine. but apparently whoever filed the bug didnt think so maik@cs.vu.nl 2008-03-24 11:12:52 0000 After adding splitdebug to my FEATURES, and recompiling glibc and valgrind 3.3.0, valgrind runs fine now. Thanks for your help! So please make sure that the ebuild for valgrind will give a message that glibc should be built with splitdebug in the FEATURES when this is not the case on the ppc64 architecture. Since many users do not know all FEATURES by heart, it is insufficient to only mention that the glibc debuginfo package should be installed, without telling that this should be done using a FEATURES flag. corsair@gentoo.org 2008-03-24 15:45:06 0000 Is ppc64 the only arch suffering from this problem. I think the error message from valgrind is sufficient. griffion26: what do you think? griffon26@gentoo.org 2008-03-24 19:44:59 0000 It's ppc32 & ppc64. I'll put a warning in the ebuild for those platforms. griffon26@gentoo.org 2008-04-30 10:15:54 0000 This was fixed 25 March, I just forgot to mark this bug RESOLVED.
