Thanks for testing. I don't have a PowerPC handy. I guess I can go find 
an emulator, but in the meantime: can you think of anything specific to 
PowerPC that might break the code? Word size? pdumper works for me in 
both 32- and 64-bit forms on x86. Endian? AIUI, PowerPC has selectable 
endianness. Are you big- or little-endian? Besides, pdumper *should* be 
endian-neutral. And if we were looking at an endianness mismatch, I'd 
expect a much bigger mismatch than 544 vs. 536. What stack do you have 
there? Does your system use natural alignment?
