Hi everybody,
I'm experiencing a weird behaviour when using va_list with gcc 4.1.2
on a x86_64 linux distribution.
Below is my test program (yes, I know about the possible buffer
overflows but please, bear with me, this is just a proof of concept):
#include
#include
int var(const char* fmt, .

Hi!
I'm interested in static stack analysis tools.
Either using someone else's or creating.
Where would I find existing tools?
Where would I find existing contracter software developers?

Hi, I have just run and timed a couple of tutorial examples for
openMP using gcc (GCC) 4.2.1 (Ubuntu 4.2.1-5ubuntu4) on a dual core
Athlon amd64, with OMP_NUM_THREADS set to 1 and 2, and occasionally
8 I found that 1 thread outperforms 2 by almost 2:1 on all the examples,
and 8 is only fractionall

Hi,
I have Ada interrupt tasks that are attached
to real hardware interrupts working for RTEMS.
I based the RTEMS code on the existing code
for VxWorks.
I tried to minimize my modifications since I
could tell that the OS functionality used was
very generic. But since the implementation

Unfortunately no, unless MSVC++ in VS2005 has openMP.

I don't know if Visual C++ 2005 Express supports OpenMP, but the
Professional edition should. Alternatively, the free, as in beer,
Microsoft compiler included in the Windows SDK supports OpenMP.
