Fatal error at startup

If you receive the following error message when you try to run Valgrind:

==23489== Memcheck, a memory error detector
==23489== Copyright (C) 2002-2013, and GNU GPL'd, by Julian Seward et al.
==23489== Using Valgrind-3.10.1 and LibVEX; rerun with -h for copyright info

valgrind:  Fatal error at startup: a function redirection
valgrind:  which is mandatory for this platform-tool combination
valgrind:  cannot be set up.  Details of the redirection are:
valgrind:  A must-be-redirected function
valgrind:  whose name matches the pattern:      strlen
valgrind:  in an object with soname matching:
valgrind:  was not found whilst processing
valgrind:  symbols from the object with soname:
valgrind:  Possible fixes: (1, short term): install glibc's debuginfo
valgrind:  package on this machine.  (2, longer term): ask the packagers
valgrind:  for your Linux distribution to please in future ship a non-

valgrind:  that exports the above-named function using the standard
valgrind:  calling conventions for this platform.  The package you need
valgrind:  to install for fix (1) is called
valgrind:    On Debian, Ubuntu:                 libc6-dbg
valgrind:    On SuSE, openSuSE, Fedora, RHEL:   glibc-debuginfo
valgrind:  Cannot continue -- exiting now.  Sorry.

it is because sys-libs/glibc (package not on wiki - please add) was built without the debug USE flag. To enable this USE flag, you can do the following:

# mkdir /etc/portage/package.use (if it doesn't exist on your system)
# touch /etc/portage/package.use/glibc
# echo "sys-libs/glibc debug" > /etc/portage/package.use/glibc
# echo 'FEATURES="splitdebug"' >> /etc/portage/make.conf

After making the required changes, simply re-emerge glibc with the following command:

# emerge --ask glibc

You should receive an output similar to the following:

Calculating dependencies... done!
[ebuild   R    ] sys-libs/glibc-2.20-r1  USE="debug*"

After re-emering glibc, Valgrind should function properly.
