I think the patch from https://hardened.gentooexperimental.org/trac/secure/changeset/0c0259995cd7ee7c618b88c61286ad344e2e5a58 should be re-added to libstdc++ in the hardened-dev overlay. I'm using the hardened-dev overlay, and after the fix added in https://hardened.gentooexperimental.org/trac/secure/ticket/78 , libstdc++ now stops building with an stack smashing error in xgcc, like repoted in https://hardened.gentooexperimental.org/trac/secure/ticket/64 . I haven't been able to test whether this actually fixes the problem, but I will report as soon as I have tested it.

Should have be fixed in the eclass/flag-o-matic.eclass _filter-hardened() Will look at it.
I tested this with the compilers from the overlay. I confirmed the bug for 4.3.4-r1. However, libstdc++ compiles fine for 4.4.1-r1. My emerge --info is in the next comment.

Commit 86d6cc741aba959b2c07fa11ce83cbcf42fbdf1e Thanks all Working on a new libstdc++-v3 see bug 231870
Still broken or closing time?
I retested libstdc++-v3-3.3.6 against the overlay gcc-4.3.4, 4.4.1 and 4.4.2. Only 4.3.4 fails without compile_with_no-SSP.patch. So the ebuild should only apply the patch for gcc-major-version = 4 and gcc-minor-version = 3. The current ebuild has: # bug 285956 Fail on GCC 4.3.3 but pass on GCC 4.4.1 if [[ get-version > 4.2 ]] ; then epatch "$FILESDIR"/compile_with_no-SSP.patch fi however, I don't think get-version works. The if line should read: if [[ "$(gcc-major-version)" = "4" ]] && [[ "$(gcc-minor-version)" = "3" ]] ; then Also, with the recent removal of libstdc++-v3-4.4.1.ebuild and libstdc++-v3-4.4.2.ebuild, we don't need libstdc++-v3-Makefile.in.patch in ${FILESDIR}. All of this has been tested on x86_64 and the resulting /usr/lib64/libstdc++.so.5.0.7 works when linked against. I'm testing now on i686. If there are no objections, I'll commit these changes to the overlay.
I tested the changes in Comment #6 on i686 as well, and it looks good.
Committed to the overlay and works fine.
