It is not normal that libiconv gives different results on different
platforms (except for the wchar_t encoding, which is determined by
the libc).

As a first step: can you show an example of a conversion that
succeeds on x86 and fails on ARM? I mean the file fa.txt (as an attachment,
or as a hexdump) and the options passed to 'iconv'.

Second, how did you build libiconv (which configure arguments, $CC,
$CPPFLAGS, $CFLAGS)?

Third, does the problem go away if you compile with less optimization
options (-O0 instead of -O2, for example)?
