Dear maintainers,
currently, two tests from wget2's test suite (test-wget-1 and
test-timestamping) may fail on 32-bit architectures due to a bug in the
setup of wget2's option parser. This might lead to misaligned memory
access as can be seen in the armhf build log [1] at least:
options.c:359:28: runtime error: store to misaligned address 0x00c1d26c for
type 'long long int', which requires 8 byte alignment
0x00c1d26c: note: pointer points here
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00

Unexpected error code 1, expected 0 [--chunk-size=3]
I have tracked down the bug to a bad typecast from '(size_t *)
&config.chunk_size' to '(long long *)'. While both 'long long' and
'size_t' have 64 bits on 64-bit architectures, their memory size differ
on 32-bit architectures: 'long long' still has 64 bits but 'size_t' has
only 32 bits.
As there is more than one way to fix it, I have opened a ticket upstream
to let the authors know about it and to discuss their preferences on how
to fix it.
Best regards,
Thomas Uhle
