Accepted binutils into lucid-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

The proposed package works for me. Note to others: you need to install the proposed version of both binutils and binutils-gold.

[Bug 582754] Re: lucid gold makes nearly all C++ applications segfault before main()
For me, many C programs compiled on lucid amd64 with binutils-gold, (starting with a pre-release and continuing thru updates) gave SIGSEGV on one of the str functions. There is no problem on a fresh install of lucid (amd64) with the normal binutils. From 'ld --version' on the two installs: Works: GNU ld (GNU Binutils for Ubuntu) 2.20.1-system.20100303 Fails: GNU gold (GNU Binutils for Ubuntu 2.20.1-system.20100303) 1.9 -- lucid gold makes nearly all C++ applications segfault before main() https://bugs.launchpad.net/bugs/582754 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 582754] Re: lucid gold makes nearly all C++ applications segfault before main()
It is worse for me. Absolutely no applications, be they C++ or C, are
linked properly. Consider this small example:
#include stdio.h
#include string.h
__attribute__((noinline))
int f(const char *a, const char *b) { return strcmp(a, b); }
int main() { printf(%x\n, f(foo, bar)); }
If you compile it dynamically, you get a segfault due to strcmp being placed in
a non-executable page.
If you compile it statically, you get the address of function _libc_start
instead of executing strcmp.
Same thing happens with strlen et al, which explains that all
applications a bit complicated will segfault before even reaching main
(due to dynamic loading relying on strlen).
This is on Lucid Lynx with binutils 2.20.1-3ubuntu5 on amd64. It was
working fine on Karmic.
