Yes, that's why I said "equivalent binary". It's a useful check because it
can tell us whether the program is using things our linux-user emulation
doesn't get right at all (examples: multiple threads; some interactions of
signals and blocking syscalls); so it divides the bug into "probably in
linux-user" vs "probably a target-arm bug".
I see you've tracked the issue down in this case, though.
