Bug Description
Binary package hint: binutils
Trying to build MySQL 5.1.46 with binutils-gold installed leads to 'gen_lex_hash' (in the mysql tree, that is run during build) to segfault.
Logs below for building Drizzle (and trying to use the resulting executable). It also segfaults.
Both of these worked fine in karmic.
removing binutils-gold at least fixes a MySQL build.

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_
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.
