Different preferences when printing through Samba
Hi there,
Would there be any reason that my HP Laserjet 6L has a totally different
preference panel when i attach it to my Linux host in stead of on the
local Windows machine? For example, all setting for multiple pages per
sheet (2-up, 4-up) are gone.
I am installing the printer with exactly the same driver in both cases.
What can be wrong? (I'm running Windows XP, Debian with Samba

[RFC] Stack overflow and optimizations
Hi Michael,
Please keep in mind non-C/C++ frontends. For example, in Rust, we promise to
avoid all undefined behavior in safe code. There is no reasonable compositional
analysis that can statically detect stack overflows (I know safety-critical
systems are subjected such analyses, but those could not reasonably be enforced
on all Rust code -- most of them just forbid recursion, for example), so

If we go by the langref, then optimizations that fold undef are also
problematic (though most C/C++

tincd without root privileges
hey,
is there a way to run tinc on a (linux) box, with a public ip,
but on which i don't have root privileges ?
the server just connects nodes (behind natted firewall) & relays
their traffic, so no need for tap/tun interface on the box itself.

GEP with a null pointer base
Dave,
Dead code elimination is generally done in a pass called dead code elimination,
Can you give concrete examples why the same would not be true for UB code elimination ?
Yes, speculatively hoisting code requires it to be UB-free, but that has nothing to do with
UBCE deleting entire blocks of code because of the existence of UB. The former requires
an analysis proving UB-absense, the

GEP with a null pointer base
Dave,
The way I see it there should be just one pass that implements
deleting UB (maybe it would come to be called UBCE), and that one pass
should have a command line option simply for the reason than all passes
should have one.

GEP with a null pointer base
David,
-fsanitize=undefined sounds great, but is not quite what I want.
I recently ran into a problem with "CodeGen/MachineSink.cpp” [*], for a target
that has to expand Select into control flow.
The original IR had two select in a row that were based on the same condition,
so the CMP that sets the FLAGS reg in the second select was MCSE’ed to the
earlier CMP in the first

The semantics of nonnull attribute
Not sure the semantics of "used" you propose is sufficient. AFAIU the proposal, "used" could only be used in cases where the function will always trigger UB if poison is passed as argument.
The semantics of attributes is usually the other way around, since function calls need to have UB as strong as the worst behavior of the function. If a function may for some reason trigger

GEP with a null pointer base
Mehdi,
Hal’s transformation only kicks in in the *presence* of UB, and
it does not matter how that UB got there, whether by function inlining
or without function inlining.
The problem with Hal’s argument is that the compiler does not have
a built in ouija board with which it can conjure up the spirit of the
author of the source code and find out if the UB was intentional

Segmentation fault issue with new install
Hi all,
I am a long-time user of Icecast, always without problems. However i made a
new setup using icecast 2.4.1 on a fresh and quick CentOS VPS.
The issue is that starting icecast gives a segmentation fault at around 80%
of all starts. No core file nor a entry in error.log is posted. In the
remaining 20% of the starts icecast start with no problem.
