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))
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
Did anyone discover this problem, or is there a workaround for this?
