Dudes, just a quick pass at this.
a.out:
/usr/lib/gcc/i386-redhat-linux/3.4.3/../../../../include/c++/3.4.3/bits/basic_string.h:643:
typename _Alloc::reference std::basic_string<_CharT, _Traits,
_Alloc>::operator[](typename _Alloc::size_type) [with _CharT = char, _Traits =
std::char_traits<char>, _Alloc = std::allocator<char>]: Assertion `__pos <
size()' failed.
Abort (core dumped)
I get this with 3.4 to mainline with -O1 or -O2.

Indeed, Benjamin, I also get this, and that't why probably the issue is not
serious as I was afraid it was. However, we are basically relying on inlining
to happen for this to work, and that's brittle (as Jonathan also pointed out).
At minimum, we have to document this behavior of string debug-mode in the docs...

Hey Paolo. I consider this fixed for mainline.
I don't want to port this to gcc-4_0-branch. First of all, this isn't a
regression since debug mode was introduced in 3.4 and refined in 4.0.x, but is
essentially the same. In addition, this turned out to be a messy area. Fixing
this took a lot, including the header work to remove cassert and moving all
those patches over to the stable branch is more movement and change than I feel
comfortable with.
So, permission to change to WONTFIX for gcc-4_0-branch and leave as fixed for
gcc-4.1.0?

This is WONTFIX for 4.0.x, but is fixed in 4.1.x and later.
