We have here struct casts, which maybe are reasoning here strict aliasing

I was not able to reproduce the bug on Linux, so I assume this is a
Windows-specific.
If an exception is generated inside shared library (DLL), then crosses the
DLL-boundary and gets caught in some other module, the std::uncaught_exception
will always return wrong (inverted) value from now on.

The following program is rejected with the bogus message that the derived type
is not interoperable - it works if one moves the type declaration out of the
interface statement. It also works with

Consider the program that follows (you can cut paste into a shell to get
foo.s). Functions A and B are mathematically identical on the reals.
On Mac OS X 10.5, gcc version 4.4.1, with -O2, we see A and B compiling
differently. In the assembly we see that A squares z, multiplies by y,
subtracts

Unfortunately, there is still no word from the FSF on what they did with our
Copyright Assignment.
As already mentioned in PR 38785, I've posted the patch here:

Ah, true; and that means that with the options I said to use, the optimization
is simply wrong. However, I see the same behaviour even with

So I did this experiment whether the stack is aligned in current Linux
binaries.
I applied this patch for gcc, so that it crashes on function entry if the
function has stack not aligned on 16

Very unfortunatelly, gcc does assume stack alignment.
The problem is not technical (the code to realign the stack is already there,
it's easy to activate it), the problem is ideological,

It looks like 4.5 will be dead-on-arrival alpha*-dec-osf[45]*, unless I fix
this myself...

One day, I built gcc 4.4.1 prerelease, with normal multilib. The next day, I
realized I forgot to add Ada, and all of a sudden multilib failed with the
exact same configuration. At the time, I didn't think too much of it and don't
remember if anything else happened between the two builds, but it

On Binutils I thought I could try an old version, but then realized trying an
old version doesn't really answer the question, it could still be in gcc's
field, or binutils causing a bug in gcc to surface, and leave the

I was not able to reproduce the bug on Linux, so I assume this is a
Windows-specific.
