I got the same problem today. I had eix 0.7.2 whether stable or not it doesnt matters. Always segfault with update-eix. +++ This bug was initially created as a clone of Bug #112826 +++ When eix is compiled using the patched hardened gcc, update-eix can't run (see below). When compiled with the vanilla-gcc it works.

This is NOT a Gentoo bugzilla product bug, read the descriptions.
I try to re-assign this bug to the hardened team, but maybe the toolchain team is more correct, because the bug might also be related to the fix of #99192. In any case, it is certainly not a particular problem of eix: The function "std::unique" (for vectors) crashes with gcc-3.4.6-r1 hardened on x86 when used with -O0. It works well with -O1 or -O2 or vanilla. Surprisingly, it does also not work on hardened when manually all optimizations mentioned in the gcc manpage for -O1 are switched on. The backtrace (even when compiled with -g -ggdb3) is completely useless. Here is some sort of minimal code example: #include <vector> #include <iostream> using namespace std; int main(int argc, char** argv) { vector<int> test; test.push_back(1); cout << "Before std::unique\n"; unique(test.begin(), test.end()); cout << "This is not reached with -O0 on hardened\n"; return 0; } To the original poster: Setting -O2 or at least -O1 in CXXFLAGS (and CFLAGS) should solve the problem, although I don't know why.

That was the trigger I guess. But we have a workaround ...

Should be fixed, re-open if not.
