I am sorry about that. I sent the message to the wrong mailing list by
mistake.

I did not know that there is a newlib mailing list. It was not available on
the Cygnus mailinglist page, so I sent the message to the cross-GCC list and
to the address in the readme (newlib@cygnus.com) and (by mistake) to the
cygwin mailing list.
Thanks for your message.

If I'm understanding your question correctly, you are attempting to use
newlib on an m68k target. If that is the case, this has nothing to
do with cygwin and is off-topic for this mailing list.
There is a newlib mailing list: newlib@sourceware.cygnus.com .
It is probably best to send your query there.

Hello,
We are using the GNU toolchain for m68k and newlib. When we are running our
SW we get a bus address error. This error occurs in strcat. The code where
the problem comes from is the following:
/* Skip over the data in s1 as quickly as possible. */
if (ALIGNED (s1))
{
unsigned long *aligned_s1 = (unsigned long *)s1;
while (!DETECTNULL (*aligned_s1))
aligned_s1++;
s1 = (char *)aligned_s1;
}
with ALLIGNED replaced with the following:
#define ALIGNED(X) (((long)X & (sizeof (long) - 1)))
The error occured in the first assignement, because s1 is not alligned.
The problems is created by the macro ALLIGNED. When X is not a multiple of 4
(for a 32 bit long) this function returns TRUE when it should return FALSE.
(BTW: this macro is also used in other modules, but there it is called
UNALLIGNED.)
Did anyone discover this problem, or is there a workaround for this?
Groeten
Johan
