------- Comment #5 from rogerio at rilhas dot com 2010-08-10 22:33 -------
Are you sure this is the way to resolve this issue? I think this will make GCC
an inferior product, as all other compilers I've tested produce correct
results. As GCC sometimes produces correct code (and in such cases it works) I
don't see anyway to get around the fact that this is, in fact, a bug.
Additionally, I've sent you an example of how to compile it in a way that it
works when compiled with GCC. Furthermore, I think most people would expect it
to work as I'm passing the address of the original parameter. I've also shown
the code for Windows where I can then use a va, but there doesn't seem to exist
an equivalent for LINUX. Even if there were an equivalent this bug would affect
its behaviour too, as I've checked the memory contents and the format string
seems to have been copied and its original address on the stack is no longer
preserved, which, of course, is wrong.
If you still decide to discard this problem I will end up with no way to work
around it and will have to definitively abandon LINUX as a software platform
because of this shortcomming of GCC (which, I repeat, is not found on other
compilers).
Thanks,
Rogerio
