samba error when browsing network.
Hello,
I've got samba 2.2.6 running on my internal network. I'm trying to
connect to my home directory via a win2ksp3 client, and i'm getting the
below error message in my satellite.log file which is the log file
created when i tried to connect. Any suggestions appreciated.
Thanks.

[RFC] Stack overflow and optimizations
During the review of https://reviews.llvm.org/D59978 we got to the
question whether we can optimize based on the assumption that stack
overflow is undefined behavior. While I think it is according to the
C++ standard, Windows Structured Exception Handling and signal
handlers might allow programs to recover/exit gracefully.
Concretely, the patch D59978 wants add the noreturn attribute to

...efined: it wraps. When -fwrapv is used, there is no
difference between
-fstrict-overflow and -fno-strict-overflow. With -fwrapv
certain types of overflow
are permitted. For example, if the compiler gets an
overflow when doing arithmetic
on constants, the overflowed value can still be used with -
fwrapv, but not otherwise.
The -fstrict-overflow option is enabled at levels -O2, -
O3, -Os.
-ftrapv
This option generates traps for signed overflow on
addition, subtraction,
multiplication operations.

[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

Issues after upgrade to 3.0.6 from 3.0.4; fixed in 3.0.7?
Hello,
I run samba 3.0.4 on a RHL9 server. Samba is a domain member of a W2k3 ADS
and I use CUPS as printing mechanism; therefore Samba is compiled with
Kerberos 1.3.1-7 and cups-devel.
3.0.4 runs pretty good, printing via CUPS runs well too, only the following
messages I see constantly (this flooding my logs) while using 3.0.4:

[LLVMdev] Overflow trap
Several instruction set architectures include arithmetic operations that can
trap on overflow, or support this feature with a separate
trap-on-overflow-flag instruction (such as the x86 INTO instruction).
I am adding a back-end to the Open Dylan compiler to generate LLVM IR. The
original back-end, which generates x86 machine code, makes use of the INTO
instruction, and the runtime turns the

String overflow with random characters
Hi, I've got a problem with a 2.2.2 samba server. It has, a number of times,
recorded the following lines for a short period of time of 10 seconds, and
then not again for days. Has anyone seen these before? It all appears to be
random characters. It has only happened from 2 machines out of 30 or so.

x.with.overflow semantics question
Hi Pete,
> Or do you mean that the result of an add may not even be defined? In
that case would reading it be considered UB in the case where the
overflow bit was set?
Yeah, this is the case I'm worried about: that for example
sadd.with.overflow(INT_MAX, 1) might be designed to return { poison,
true } instead of giving a useful result in the first element of the struct.

[LLVMdev] Overflow trap
After chatting on IRC, Peter wants a very specific interrupt (int4 on x86). I suggested he add a new llvm.x86.int(i32) intrinsic, and use the existing branch on llvm.sadd.with.overflow intrinsic. The x86 backend can then turn jo+int4 into into when reasonable.
