The latter of these fails due to a mismatch between signed and
unsigned char. The test uses
(char)200 == [val1 charValue]
The result of charValue is signed char, but char is unsigned by
default on powerpc.
Thanks ... I just changed the test to be '(signed char)200 == [val1
charValue]' since, for consistency, charValue always returns a
signed char.
Thanks. This test now passes on PowerPC linux. As for the other two
failures, it looks like an endianness issue. Adding two log statements
NSLog(@" decoded object = %@", [decodedInstance objectAtIndex: 0]);
to decoding.m the interesting part of the output becomes:

As you can see, byte order in the NSData objects is swapped in the
failed tests, which is sort of strange -- after all no byte swapping
should occur on a big-endian architecture as far as I recall.
