: I have no clue where to start debugging now.
The following are issues for arm that are differences with x86:
o unaligned access (which I think generates a SEGV, not BUS)
o Different packing and alignment of data structures causing
mismatches between x86 and arm representations (x86 may
match external ones, while arm doesn't w/o __packed).
o Characters are unsigned on arm and signed on i386.
You might want to try a ppp with symbols to see where it is dying.
