A simple testcase to check if the attribute aligned works, fails on
i386-darwin-apple:
#include
#include
int array[4128] __attribute__((aligned( 2<<6)));
int main(void)
{
__SIZE_TYPE__ a = (__SIZE_TYPE__)(&array[0]);
printf("%d\n", (int)(__SIZE_TYPE__)a & ((2<<6) - 1));
if((__SIZE_TYPE__)(

This test should not be tested on darwin as darwin does not support the popcntb
assembly instruction as none of the supported machines have that instruction.

I also see the same failure for popcount-1.c. The compile line...

The scan-assembler popcntb section of the gcc.target/powerpc/parity-1.c

Andrew,
Changing the testcase to...
extern "C" void abort();
struct A
{
double a;
} sa;
struct B
{
double b;
char c;
} sb;
int main()
{
if (__alignof (sa) != __alignof (sa.a)
|| __a

I would also note that the testcase passes at both -m32 and -m64 as I posted.
If I change...
return -(t>>5);
to
return -(t>>1);
The testcase passes at -m64 but fails at -m32. However if I use...

This seems to be a critical issue causing a thread pool implementaion to go
into dead lock and normally happens if code inside run method does requires
little time and large number runnable objects are assigned to thread pool...
I have identified this issue in sun solaris 2.9

The attached preprocessed source ICEs with current g++ 4.3 :
../../include/CGAL/Visibility_complex_2/Antichain.h:1394: internal compiler
error: Bus error
I really believe the code is valid, as it works with older g++ releases
(although the preprocessed code attached does not, but it is due to
lib
It's my first bug here, so I may be missing something.
Using built-in specs.
