I need to admit I have no idea why

fseeko() on reference file: Invalid argument

is happening on some architectures.

According to the manpage of fseek(), which is identical to fseeko() apart from the offset data type:

ERRORS [...] EINVAL The whence argument to fseek() was not SEEK_SET, SEEK_END, or SEEK_CUR. Or: the resulting file offset would be negative.

I suspect that something is calling fseeko() with a negative offset.

I'd recommend doing an strace on the specific test binary that fails on a porterbox (e.g. armhf) + on amd64 for comparison and then look for the offending fseeko() call. That might help isolate the issue.
